More about mass

General information

Mass is the property of physical bodies to resist acceleration. Mass, unlike weight, does not change depending on the environment and does not depend on the gravitational force of the planet on which this body is located. mass m determined using Newton's second law, according to the formula: F = ma, where F is power, and a- acceleration.

Mass and weight

In everyday life, the word "weight" is often used when talking about mass. In physics, weight, unlike mass, is a force acting on a body due to the attraction between bodies and planets. Weight can also be calculated using Newton's second law: P= mg, where m is the mass, and g- acceleration of gravity. This acceleration occurs due to the force of attraction of the planet near which the body is located, and its magnitude also depends on this force. Acceleration of free fall on the Earth is equal to 9.80665 meters per second, and on the Moon - about six times less - 1.63 meters per second. Thus, a body weighing one kilogram weighs 9.8 Newtons on Earth and 1.63 Newtons on the Moon.

gravitational mass

The gravitational mass shows what gravitational force acts on the body (passive mass) and with what gravitational force the body acts on other bodies (active mass). With an increase active gravitational mass body, its force of attraction also increases. It is this force that controls the movement and arrangement of stars, planets and other astronomical objects in the universe. The tides are also caused by the gravitational forces of the Earth and the Moon.

With the increase passive gravitational mass the force with which the gravitational fields of other bodies act on this body also increases.

inertial mass

Inertial mass is the property of a body to resist motion. It is precisely because the body has mass that a certain force must be applied to move the body from its place or change the direction or speed of its movement. The larger the inertial mass, the greater the force required to do this. The mass in Newton's second law is precisely the inertial mass. The gravitational and inertial masses are equal in magnitude.

Mass and relativity

According to the theory of relativity, the gravitating mass changes the curvature of the space-time continuum. The larger such a mass of a body, the stronger this curvature around this body, therefore, near bodies of large mass, such as stars, the trajectory of light rays is curved. this effect in astronomy is called gravitational lenses. On the contrary, far from large astronomical objects (massive stars or their clusters, called galaxies), the movement of light rays is rectilinear.

The main postulate of the theory of relativity is the postulate of the finiteness of the speed of light propagation. Several interesting implications follow from this. First, one can imagine the existence of objects with such a large mass that the second cosmic velocity of such a body will be equal to the speed of light, i.e. no information from this object will be able to get to the outside world. Such space objects in the general theory of relativity are called "black holes" and their existence has been experimentally proven by scientists. Secondly, when an object moves at a near-light speed, its inertial mass increases so much that the local time inside the object slows down compared to time. measured by stationary clocks on Earth. This paradox is known as the “twin paradox”: one of them goes on a space flight at near-light speed, the other remains on Earth. Upon returning from a flight twenty years later, it turns out that the twin astronaut is biologically younger than his brother!

Units

Kilogram

In the SI system, mass is measured in kilograms. The kilogram is determined based on the exact numerical value of Planck's constant h, equal to 6.62607015 × 10⁻³⁴, expressed in J s, which is equal to kg m² s⁻¹, and the second and meter are determined by exact values c and Δ ν Cs. The mass of one liter of water can be approximately considered equal to one kilogram. The derivatives of the kilogram, gram (1/1000 of a kilogram), and ton (1000 kilograms) are not SI units, but are widely used.

Electron-volt

An electron volt is a unit for measuring energy. Usually it is used in the theory of relativity, and the energy is calculated by the formula E=mc², where E is the energy m- weight, and c is the speed of light. According to the principle of equivalence of mass and energy, the electron volt is also a unit of mass in the system of natural units, where c equals one, which means that mass equals energy. Basically, electronvolts are used in nuclear and atomic physics.

Atomic mass unit

Atomic mass unit ( a. eat.) is for the masses of molecules, atoms, and other particles. One a. e.m. is equal to 1/12 of the mass of a carbon nuclide atom, ¹²C. This is approximately 1.66 × 10 ⁻²⁷ kilograms.

Slug

Slugs are used primarily in the British imperial system of measurement in the UK and some other countries. One slug is equal to the mass of a body that is moving at an acceleration of one foot per second per second when a force of one pound force is applied to it. This is approximately 14.59 kilograms.

solar mass

Solar mass is a measure of mass used in astronomy to measure stars, planets and galaxies. One solar mass is equal to the mass of the Sun, that is, 2 × 10³⁰ kilograms. The mass of the Earth is about 333,000 times less.

Carat

Carats measure the mass of precious stones and metals in jewelry. One carat is equal to 200 milligrams. The name and the value itself are associated with the seeds of the carob tree (in English: carob, pronounced carob). One carat used to be equal to the weight of a seed of this tree, and buyers carried their seeds with them to check if they were being deceived by sellers of precious metals and stones. The weight of a gold coin in ancient Rome was equal to 24 carob seeds, and therefore carats began to be used to indicate the amount of gold in the alloy. 24 carats is pure gold, 12 carats is half gold alloy, and so on.

Gran

The gran was used as a measure of weight in many countries before the Renaissance. It was based on the weight of grains, mainly barley, and other crops popular at the time. One grain is equal to about 65 milligrams. It's a little over a quarter carat. Until carats became widespread, grains were used in jewelry. This measure of weight is used to this day to measure the mass of gunpowder, bullets, arrows, as well as gold foil in dentistry.

Other units of mass

In countries where the metric system is not accepted, British imperial system mass measures are used. For example, in the UK, USA and Canada, pounds, stone and ounce are widely used. One pound is equal to 453.6 grams. Stones are mainly used only to measure the mass of a person's body. One stone is approximately 6.35 kilograms or exactly 14 pounds. Ounces are mostly used in cooking recipes, especially for foods in small portions. One ounce is 1/16 of a pound, or approximately 28.35 grams. In Canada, which formally converted to the metric system in the 1970s, many products are sold in rounded imperial units such as one pound or 14 fl oz, but are labeled by weight or volume in metric units. In English, such a system is called "soft metric" (eng. soft metric), in contrast to the "hard metric" system (eng. hard metric), which indicates the rounded weight in metric units on the packaging. This image shows "soft metric" food packages showing weight in metric units only and volume in both metric and imperial units.

Folic acid is one of the vital vitamins. As a rule, there is not so much of it in the usual diet, so vitamin B9 deficiency is far from uncommon. To replenish the balance, you need to know the correct dosage of folic acid and be able to properly use additional folates.

Vitamin B9 (medical name - folic acid) is one of the most important nutrients for humans, which is needed for many processes in the body. Folic acid helps cells grow, maintain the integrity of DNA, so the vitamin prevents the development of cancer.

In addition, folic acid is involved in hematopoiesis, helps the heart and blood vessels. By improving blood circulation, acid has a beneficial effect on immunity, improves the functioning of the nervous system and the general condition of the body.

BY THE WAY
Our intestines can produce folic acid on its own, but in very small amounts, so the bulk of this vitamin must come from food.

Reception features

Like any other drug, folic acid should be taken regularly. At the same time, consider its interaction with other drugs. For example, acid reduces the effect of phenytoin, therefore, its dose must be increased.

A number of substances reduce the absorption of folic acid by the body:

Antacids
cholestyramine,
some antibiotics (sulfonamides, chloramphenicol, tetracyclines, neomycin, polymyxin)

Reduce the effect of the action can also:

cytotoxic drugs ( Methotrexate),
antibacterial agents (pyrimethamine),
diuretics (Triamterene).

With this option, doctors prescribe calcium folinate instead of folic acid.

How to take for prevention

For prophylaxis, small daily doses of B9 are used: 400 mcg for adult.

Teenagers this dosage may be prescribed for the prevention of anemia, immunodeficiency, and physical retardation.

Women planning a pregnancy, it is recommended to use 1 mg of acid once a day for medicinal purposes for six months in order to reduce all kinds of fetal malformations.

When is the best time to take

"Folk" must be taken orally after meal, as indicated in all instructions for the drug.

The fact is that taking vitamins on an empty stomach can lead to irritation of the gastric mucosa: like other acids, folic acid increases its acidity. This provokes diseases of the stomach - gastritis, ulcers, etc.

If you take a vitamin while eating, food will be more difficult to digest, since the acid forms an insoluble complex with zinc.

Important: if you miss a pill, you do not need to take a double dose

Admission courses

To maintain optimal levels of folic acid in the body, a daily intake is necessary.

ADVICE:
It is better to drink any vitamins in the morning during breakfast, drinking plenty of fluids. So unabsorbed vitamin surpluses can be easily removed by the body

How many folic acid tablets per day should I take

The number of tablets depends on the mass of the active substance in it, since folic acid is now sold in different dosages.

Most often, pharmacies sell folic acid in a dosage of 1 mg. For medicinal purposes, you need to use 1-2 tablets. per day. Pregnant women - 1 tablet per day for prevention.

Folic acid and vitamin E: regimen

Vitamin E and folic acid - a couple of useful elements that complement each other. Most often, gynecologists prescribe this combination of vitamins to girls from the first stages of pregnancy or to those who are just planning it.

Vitamin E and B9 guarantee the full development of the internal organs of the child and the development of the central nervous system. Vitamin E is directly responsible for the reproductive system, increases the fertility of the girl, reduces the threat of miscarriage in the short term, and prevents the placenta from exfoliating.

When used with folic acid, the intestinal wall is strengthened, the mother's condition improves: working capacity increases, immunity increases, the nervous system is restored.

Optimal dosage:

Vitamin B9 (folic acid) - 0.8 mg per day.;
Vitamin E (tocopherol) - 0.3 mg per day..

Is it possible to drink folic acid without a prescription

Any pharmacy will tell you that this medicine is available without a doctor's prescription.

If you find yourself deficient in folic acid, then the smallest daily dose will not harm you, since the excess is excreted by the body on its own.

The best option is dietary supplements, where the composition already contains folic acid. Like vitamin complexes, dietary supplements contain many other useful substances.

ADVICE :
The daily volume of folic acid is determined by various factors: gender, age, lifestyle and body condition; Only a doctor can help you choose.

Despite the widespread belief that folate is easily excreted from the body and its overdose is impossible, it should be borne in mind that the vitamin has a number of contraindications:

hypersensitivity to B9,
malignant anemia,
oncology,
vitamin B12 deficiency.

Release form

Folic acids in pharmacies can be found in the form of powders or tablets (usually 1 mg, 25 and 50 pieces per pack).

However, there are other forms of release:

100 mcg

the minimum dosage may be prescribed by a doctor for prevention;
100 mcg is how many mg: 0.1 mg

400 mcg

dosage in tablets 400 mcg:
1 tab. per day (if there is no deficiency), or half a tablet (1/2 tablet of acid) at a dosage of 1 mg per day - for children over 4 years old and adults as maintenance treatment; pregnant women to prevent fetal defects
400 mcg is how many mg: 0.4 mg;
folic acid 400 mcg how many tablets:
1 tab. a dosage of 400 mcg or a quarter of a tablet with a dosage of 1 mg is the recommended daily dose for women of childbearing age and during pregnancy.

800 mcg

dosage in tablets 800 mcg:
1 tab. or slightly less than 1 tab. a dosage of 1 mg is prescribed during pregnancy and lactation.
800 mcg is how many mg: 0.8 mg

dosage in 4 mg tablets:
attributed when planning pregnancy. There is no need to be afraid of such doses: if the doctor has prescribed this volume for you, then you or your baby do not have enough B9

5 mg

dosage in tablets 5 mg:
adults 1 tab. per day for the treatment of beriberi, children - in smaller doses depending on age
5 mg is how many grams: 0.005 g

Dosage of folic acid for children

Folic carbon dioxide is necessary for the growth and proper development of the body, because the body's immunity is developed directly in childhood, the main life-supporting systems are formed, so it is important to give the child all the necessary vitamins for its construction.

baby

Infants are recommended 25 micrograms of folic acid each day. With normal development, the baby receives all the nutrients from mother's milk, but if the doctor has identified a lack of nutrients in the newborn, B9 is prescribed additionally. Often, folic acid is required for premature babies.

Teenager

At a transitional age, B9 is necessary for children for the normal course of sexual development: vitamin B9 helps the young body to establish hormonal balance. In adolescence, many face skin problems of the face and body: acne, pimples, redness. With the help of folic acid, you can fight redness and irritation of the skin.

For the prevention of vitamin deficiency, children at this age are recommended to use 150-200 mcg, this is half a tablet with a dosage of 400 mcg. But we must remember that if the body needs to be restored, then the therapeutic dose of acid is determined by the doctor.

schoolboy

Folic acid for school-age children from 6 to 10 years old is prescribed at a dosage of 100 mcg per day; from 10 to 14 years - 150 mcg.

Schoolchildren need vitamin B9 to regulate brain activity in order to help children cope with the study load and relieve emotional stress.

How much folic acid do children need: summarizing

Daily Value for Women

To maintain the balance of vitamins in the body, an adult woman needs to take at least 400 micrograms of folate per day.

In addition to the fact that vitamin B9 strengthens the body, normalizes internal processes and improves the general condition, folic acid (folka, as mothers like to call it) is of particular importance for women:

beneficial effect on the reproductive organs,
stops hair loss, rejuvenates and tones the skin;
normalizes the hormonal background;
reduces the symptoms of menopause;

How many times to take per day

Doctors advise taking folic acid (vitamin B9) like all other vitamins according to the scheme: 1 time per day, preferably in the morning, with meals. Drink a small amount of water.

Daily allowance for pregnancy planning

Pregnant doctors necessarily attribute folates. Normally, a woman should receive 400-600 micrograms of acid per day, this is half a 1 mg tablet.

Daily allowance for pregnant women

How many weeks to take folic acid?

Due to the fact that folates do not accumulate in the body, acid is needed already in the first weeks of pregnancy, doctors recommend taking it even at the planning stage of the baby.

IMPORTANT!A woman's body needs vitamin B9 the most in the first 12 weeks of pregnancy.

Daily allowance for breastfeeding mothers

When breastfeeding, a young mother should drink this medicine with a dosage of at least 500-800 micrograms of "folk" per day. It is better to take it as part of dietary supplements or multivitamins, since not only the mother's body, but also the baby needs nutrients at this moment.

Daily Value for Men

If the male body receives at least 700 micrograms of folic acid daily, then the risk of spermatozoa with different types of abnormalities in the chromosomes is reduced by 25-30%.

To avoid infertility in men, B9 is advised to be taken in conjunction with vitamin E.

When a couple is planning a pregnancy, a man needs to drink folic acid 2-3 months in advance.

Conclusion

Vitamin B9 ( in other words folic acid) participates in the formation of the circulatory system and immunity.
Folic acid is essential women who decided get pregnant, as it participates in the normalization of the process of formation and development of the fetus.
folic acid for men necessary for the good functioning of the digestive tract, improving memory, as well as increasing fertility.
Folic acid is prescribed children to improve appetite, brain function and boost immunity.

Clinical and pharmacological group

An antiproliferative drug for the treatment of psoriasis

pharmachologic effect

Calcipotriol is an analogue of vitamin D. It stimulates morphological differentiation and inhibits the proliferation of keratinocytes, which underlies its therapeutic effect in psoriasis.

Calcipotriol is a potent inhibitor of interleukin I-induced T-lymphocyte activation.

The effect of calcipotriol on calcium metabolism is 100 times weaker than with the use of the hormonally active form of vitamin D 3 .

Pharmacokinetics

Transdermal absorption of calcipotriol is, depending on the dose used, from 1% to 5%. Calcipotriol undergoes rapid biotransformation in the liver with the formation of pharmacologically inactive metabolites.

T 1/2 is very short.

Indications for the use of the drug

- psoriasis vulgaris (including chronic psoriasis of the scalp).

Dosing regimen

Ointment

For adults the maximum daily dose should not exceed 15 g, the maximum dose per week - no more than 100 g. The ointment is applied in a thin layer to the affected skin 2 times / day. The therapeutic effect is usually observed after 1-2 weeks from the start of treatment. The duration of the course of treatment is no more than 6-8 weeks.

For children over the age of 12 the maximum dose per week should not exceed 75 g. The ointment is applied in a thin layer to the affected skin 2 times / day.

For children aged 6 to 12 the maximum dose per week is not more than 50 g. The ointment is applied in a thin layer to the affected areas of the skin 2 times / day.

Cream

For adults the maximum daily dose should not exceed 15 g, the maximum dose per week - no more than 100 g. The cream is applied in a thin layer to the affected skin 2 times / day. The therapeutic effect is observed after 1-2 weeks from the start of treatment. The duration of the course of treatment is no more than 6-8 weeks.

Solution

For adults the maximum total dose per week should not exceed 60 ml. A small amount of the solution is applied to the affected areas of the scalp 2 times / day (morning and evening).

Side effect

Dermatological reactions: the most typical are local skin irritation; typical - erythema and itching of the skin; atypical - dermatitis (including dermatitis of the skin of the face and perioral when using the solution), exacerbation of psoriasis; very rare - hyperpigmentation, photosensitivity.

From the side of metabolism: very rare - hypercalciuria, hypercalcemia.

Allergic reactions: in some cases - angioedema and swelling in the face (when using the drug in the form of a solution).

Contraindications to the use of the drug

- diseases accompanied by a violation of calcium metabolism;

- Hypersensitivity to the components of the drug.

FROM caution the drug should be used for hypercalcemia, hypercalciuria, hypervitaminosis D, nephrolithiasis, in children when prescribing a cream and solution (under the age of 6 years - when prescribing an ointment) due to lack of application experience; in patients over 65 years of age.

The use of the drug during pregnancy and lactation

The use of the drug during pregnancy and lactation should be avoided. The safety of the drug during pregnancy and lactation has not been established. It is not known whether calcipotriol is excreted in breast milk.

special instructions

Before use, you should consult with your doctor.

To avoid contact of the drug with the skin of the face, hands should be washed thoroughly after each application of the ointment, cream or solution.

Hypercalcemia develops when the maximum dose of calcipotriol per week is exceeded. When the drug is discontinued, the concentration of calcium in the blood quickly returns to normal.

If the solution is used together with an ointment or cream, it should be borne in mind that the total dose of calcipotriol should not exceed 5 mg per week, which corresponds to 60 ml of solution and 40 g of ointment or cream, or 40 ml of solution and 60 g of ointment or cream (1 ml of solution corresponds to 1 g ointment or 1 g cream).

During treatment with Daivonex, doctors recommend that patients limit or avoid excessive exposure to natural or artificial sunlight. Topical calcipotriol should only be used with UV light if the physician and patient consider that the potential benefit outweighs the potential risk.

Influence on the ability to drive vehicles and control mechanisms

Daivonex ® does not affect the ability to drive vehicles and control mechanisms.

Overdose

Symptoms: when using the drug in doses exceeding those recommended, it is possible to increase the concentration of calcium in the blood.

Treatment: drug withdrawal.

drug interaction

Daivonex ® should not be used concomitantly with topical preparations containing salicylic acid.

Terms of dispensing from pharmacies

The drug is approved for use as a means of OTC.

Terms and conditions of storage

The drug should be stored at a temperature not exceeding 25 ° C, out of the reach of children. Shelf life - 2 years.

From arithmetic we know that 1 g is a multiple of 1 kg, that is, a thousandth of a kilogram. And when you need to find out how many grams are in a kilogram, we multiply the figure denoting kilograms by a thousand and get:
1 kg x 1000=1000 g, or 1 kg=103 g.

So, a milligram is also a thousandth of a value, which is called a gram.

And similarly, the problem is solved when you need to find out how many milligrams are in it.
We attribute three zeros to the number that indicates the amount of g.

1 g x 1000=1000 mg, or 1g=103 mg. Here is such a simple answer to the question - how many mg are in 1 gram.

Putting knowledge into practice

Life constantly confronts us with a situation where we have to solve such arithmetic problems. Most often, this occurs when taking medications.

For example, if the instructions for use say that more than 0.2 g of the drug should not be consumed per day, and the weight of 25 mg is indicated on the tablets in the blister, then you need to find out how many tablets can be used.

Solution algorithm: 0.2 g x1000 = 200 mg, 200 mg: 25 mg = 8 tablets.

But the reverse conversion from milligrams to grams is also common, especially when cooking or for chemical solutions for household purposes.

We remember that if 1 g = 103 mg, then 1 mg = 10-3 g or 1 mg = 0.001 g.
Suppose, according to the recipe, we need to add 300 mg of granulated sugar and 800 mg of salt somewhere, and our scales measure only g.

International unit (IU)- in pharmacology, it is a unit of measurement of the amount of a substance, based on biological activity. Used for vitamins, hormones, certain drugs, vaccines, blood constituents and similar biologically active substances.

How many milligrams in a gram?

Despite the name, the IU is not part of the international SI measurement system.

The exact definition of one IU varies for different substances and is established by international agreement. The Committee for Biological Standards at the World Health Organization provides reference blanks for certain substances, (arbitrarily) sets the number of IUs they contain, and defines biological procedures for comparing other blanks with reference blanks. The aim of such procedures is that different preforms having the same biological activity contain an equal number of IUs.

For some substances, over time, mass equivalents of one IU were established, and measurement in these units was officially abandoned. However, the IU unit may still remain in wide use due to convenience. For example, vitamin E exists in eight different forms that differ in their biological activity. Instead of specifying the exact type and weight of the vitamin in the preparation, it is sometimes convenient to simply indicate its amount in IU.

Wikipedia

International unit (IU)— internationally agreed standards needed to compare the levels of different biological compounds tested on the basis of their potency.

If purification by chemical methods is not possible, the substance is analyzed by biological methods, and a stable standard solution is used for comparison. Serum standards are held at the State Serum Institute (Copenhagen, Denmark), at the National Institute for Medical Research (Mill Hill, UK) and at the World Health Organization (WHO) (Geneva, Switzerland).

international unit set as a specified amount of standard solution (for example, one IU of tetanus antitoxin = 0.1547 mg of standard solution, which is stored in Copenhagen).

Pharmacology And Pharmacotherapeutics (New Revised 21st Ed.)

5 milligrams is how much?

What is the difference between 5 mg and 5 ml?

People quite often confuse two completely different concepts: a milliliter and a milligram. Some people think they are one and the same. So let's figure it out.

First, you need to determine which dosage form before us.

Solids are dosed by weight (weighed out), while liquids are dosed by volume (measured).

In the first case, the unit of measure is gram\milligram\microgram, and in the second case it is liter\milliliter.

Dosing by weight

Weight designations :

1.0 - 1 g (gram)

0.001 - 1 mg (milligram)

0.000001 - 1 μg (microgram)

Measuring weights, weights, scales (according to the principle of weighing, there are: spring, lever, manual, platter and others).

Measuring tools for the consumer: the measure of measurement in this case will be the dosage of the drug prescribed by the doctor. We discussed dosages in more detail in article.

Dosing by volume

Volume designations:

1 ml - 1 milliliter

1 l - 1 liter

Measuringmanufacturer tools: volumetric and pharmacy pipettes, volumetric flasks, cylinders, beakers, burettes.

Measuring tools for the consumer: caps, pipettes, syringes, cups, measuring spoons.

Fix:

What does the sign say 1,0 ?

Answer: This is the mass of a substance weighing in 1 gram.

Clarification: If we are talking about the volume of the dosage form, then next to it will be the designation - ml, that is 1.0 ml(or simply 1 ml).

How to calculate the required number of drops?

The non-standard unit of volume is a drop.

How many milligrams are in 1 gram?

This is an inaccurate indicator for calculations, because the volume of a drop depends on the physical properties of the dispensed liquid.

For comparison: the volume of 1 drop of an alcohol solution is on average 0.02 ml, and for an aqueous solution it can vary from 0.03 to 0.05 ml.

Pharmacists and doctors have decided to jointly designate a standard measure for this unit of measurement. It is generally accepted that the volume of 1 drop is 0.05 ml.

When the dosage of the medicinal product in drops is prescribed, it is understood that the volume of one drop is 0.05 ml. If you have a medical syringe with a volume of 1 ml at home, then you can easily determine the required amount of medicine: 2 drops - 0.1 ml, 3 drops - 0.15 ml, 5 drops - 0.25 ml.

spoons are also an inaccurate measuring device for determining the volume of the dosage form. For them, the conventions of volume are also accepted.

Memo when dosing liquid dosage forms:

1 cap. (drop) = 0.05 ml

2 cap. \u003d 0.1 ml (we measure with a syringe, 1 ml in volume)

20 cap. (with a pipette) = 1 ml

1 tsp (teaspoon) = 5 ml

How many milligrams are in one gram?

Well, if you remember, but there are people who have forgotten this information. Let's not blame them - a person is not able to store in his head all the data that he once received. And here's the answer to the question.

A milligram is a unit of mass in the international SI system of units. A milligram is one thousandth of a gram (or one millionth of a kilogram). It turns out that 1 g of the substance contains 1000 mg. 1 milligram, in turn, contains 0.001 g of the substance.

Easy to remember?

Quite. However, in practice we often meet with cases that often lead us into a stupor. A simple example: you need to take a pill. The packaging says that the weight of each tablet is 0.25 g, while you need to take 750 mg. Since we already know that one gram contains a thousand milligrams, we simply translate the values. So, 0.25 g is 250 mg. Divide the prescribed 750 mg by 250 mg and get the number 3. Three - that's how many pills you need to take.

Of course, you can transfer everything back. 750 mg is 0.75 g. The tablet weighs 0.25 g. Divide 0.75 g by 0.25 g and get the same figure - 3. As you can see, everything is quite easy and simple, but if you have any questions on this topic, you can ask them to us using the comments section.

When working with small quantities of a substance, the unit of mass used is often the milligram (mg). A milligram is a thousandth of a gram. that is, one gram contains one thousand milligrams. In order to convert grams to milligrams, you don’t even need a calculator - quite elementary knowledge in arithmetic.

Instruction

1. In order to convert grams to milligrams, multiply the number of grams by 1000. That is, use the further primitive formula: Kmg \u003d Kg * 1000, where Kmg is the number of milligrams, Kg is the number of grams. So, let's say, the mass of one tablet of activated carbon is 0.25 grams. Consequently, its mass, expressed in milligrams, will be: 0.25 * 1000 = 250 (mg).

2. If the number of grams is an integer, then to convert grams to milligrams, primitively add three zeros to it on the right. Let's say one tablet of ascorbic acid with glucose weighs 1 gram. So, its mass in milligrams will be: 1,000.

3. If the number of grams is expressed as a decimal fraction, move the decimal point three digits to the right. Let's say the table of contents of glucose in one tablet of ascorbic acid with glucose is 0.887 grams. Consequently, in milligrams, the mass of glucose will be 887 mg.

4. If there are less than 3 digits later than the comma, complete the missing signs with zeros. So, let's say, the table of contents of ascorbic acid in one tablet of ascorbic acid with glucose is 0.1 gram. In milligrams, this will be - 100 mg (according to the rule, it turns out 0100 mg, but the leading zeros on the left are discarded)..

5. If all the initial data are given in grams, and the result must be presented in milligrams, then carry out all intermediate calculations in grams, and translate milligrams only the result of the calculations. So, let's say, one tablet of allochol contains: - dry bile - 0.08 g, - dried garlic - 0.04 g, - nettle leaves - 0.005 g, - activated carbon - 0.025 g. In order to calculate: how many milligrams of energetic substances are contained in one tablet of allochol, add up the masses of all components, expressed in grams, and translate the total into milligrams: 0.08 + 0.04 + 0.005 + 0.025 = 0.15 (g). 0.15 * 1000 = 150 (mg).

Gram is a unit of mass measurement belonging to the system of metric measures. Gram is one of the main units of the system of unconditional measures of the CGS (centimeter, gram, second) - widely used before the adoption of the international system of measurement (SI). Denoted as g or g.

How many milligrams are in one milliliter

Multiple unit of mass kilogram is one of the basic SI units, denoted by kg or kg.

Instruction

1. Gram is equal to the mass of one cubic centimeter of water at the temperature of its maximum density (4°C). As a measure of body weight, the gram is a derived unit in the metric system. It is one thousandth of a rod unit of mass - kilogram a. The kilogram was defined (with an accuracy of 0.2%) as the mass of one cubic decimeter (0.001 cubic meter) of water at its highest density temperature. At the current time to determine the mass kilogram and the International Bureau of Weights and Measures in Paris keeps the standard kilogram a - a cylinder about 39 mm high, made from a platinum-iridium alloy in 1889.

2. Gram equal to one thousandth kilogram and (1 g \u003d 0.001 kg), therefore, to translate the known body weight, which is given in grams, you need to multiply it by 1000.
