How many milligrams are in a gram? How many milligrams are in a gram 150 milligrams how much

When we finish our training, we often forget a lot of what we went through in the program. For example, not everyone remembers how many milligrams are in a gram. However, this knowledge is sometimes simply necessary in everyday life. For example, the correct dosage of various components in cooking, medicine, and cosmetology often depends on how well we have mastered the system for converting weight from kilograms to grams, from grams to milligrams. If you take this lightly, you can easily ruin the result. After all, it is much easier to figure out how much to add and where, knowing how many milligrams are in a gram. Small values are often used when working with small volumes of substances, and it is very important not to confuse the ratio. Even on the Internet, you can sometimes come across statements that confidently say that a gram contains 100 milligrams. But it is quite possible that, after reading such a post, another person will simply make a mistake with his calculations. So, how many milligrams are in a gram? And how to do the calculations correctly?

A milligram is a thousandth of a gram. The value of the prefix "milli" means 10 to the -3 power, respectively, indicating one thousandth. That is, one gram consists of one thousand milligrams. In fact, it is not at all difficult to convert these values even without a calculator. To do this, it is enough to use the most basic knowledge of arithmetic.

To make it easier to understand how many milligrams are in 1 gram, I will present a clear example:

1 gram is equal to 1,000 milligrams

And vice versa:

1 milligram is equal to 0.001 grams

It follows that:

1 kilogram is equal to 1,000 grams, which is equal to 1,000,000 milligrams

Using such a simple table, you can correctly calculate the amount of substances.

Knowing how many milligrams are in one gram is necessary if you want to correctly follow recipes for various cosmetics and medications. After all, situations often arise when we can independently understand all the subtleties and nuances, but ignorance of how many milligrams are in a gram and well-founded uncertainty about the correctness of the calculations prevents us from finding a rational solution.

Let's say you need to give medicine to a small child. But it is known that the dosage of some drugs differs quite strictly between adults and children. In this case, the most difficult thing is to choose the required dose that will not cause any side effects or negative health effects for very young children, up to three years old. Having a whole tablet and knowing its standard weight, as well as the amount of active substance, you can easily do this. In an example it looks like this.

Tablet weight is 500 milligrams. The pediatric dose of this drug is 0.25 grams. Difficult? Not at all. One has only to use the elementary school formula and everything will fall into place. You can use two different ways to convert values - from grams to milligrams or vice versa. This is what the result will be:

500 milligrams = 0.5 grams. And you only need 0.25. We divide the tablet into two parts and get the required dose of the required medicine.

You can do the other way around:

0.25 grams = 250 milligrams

The result is two numbers - 500 milligrams and 250 milligrams. And now it is much easier to understand how to properly split the tablet.

I will give a few more examples of converting grams to milligrams and vice versa.

0.12 grams = 120 milligrams.

540 milligrams = 0.54 grams

0.03 grams = 30 milligrams

36 milligrams = 0.036 grams

Here's how you can easily deal with such incomprehensible quantities. There is no need to divide or multiply if you correctly understand the number of zeros. In the version with 540 milligrams, 0.54 grams can be obtained by simply moving the separating comma three digits forward, which means three zeros in 1000. After all, did you remember that there are 1000 milligrams in one gram? And in the case of converting 0.03 grams to milligrams, the comma is moved back three digits and the missing zero is added. 0.030 = 30.

A milligram is a thousandth of a gram. The value of the prefix "milli" means 10 to the -3 power, respectively, indicating one thousandth. That is, one gram consists of one thousand milligrams.

You can’t just convert milligrams into teaspoons. As far as I understand, the medicine is liquid? And every solution has a concentration. that is, there is a certain amount of substance in a certain volume of solution. First you need to understand how much (in milligrams) of the substance is contained in a milliliter, liter, or one hundred milliliters of solution. only then calculate how many milliliters to take so that it is 200 mg. Now about spoons: everyone’s spoons are different. Having understood how much volume you need, measure it with the same syringe. It is inconvenient to do this constantly, so “calibrate” the spoon by once pouring the required volume into it and noticing the level.

Baby, are you sick??? I'll be there soon!!!

HOW MUCH MEDICINE IS IN A TINCTURE OR SOLUTION? For liquid dosage forms, the dosage is often indicated per 1 teaspoon (5 ml). Example: the doctor prescribed taking the medicine in the form of a syrup or suspension. On the package or in the annotation it is indicated - 15 mg / 5 ml. This means that 1 teaspoon contains 15 mg of the drug. Accordingly, if you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at one time. Often in liquid dosage forms the content of the drug in the entire volume of the solution or syrup is indicated. Example: the annotation states that the bottle contains 80 mg of the active substance, and the packaging is 160 ml. In this case, it is recommended to take the drug 1 teaspoon 2 times a day. We are calculating the dose per 1 ml: for this, the dose of the substance in the entire volume must be divided by the entire volume of liquid. That is: 80 mg / 160 ml = 0.5 mg in 1 ml. Knowing that a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 X 5 mg = 2.5 mg. Therefore, 1 teaspoon (single dose) contains 2.5 mg of active ingredient.

How many milligrams are in 1 gram: calculation and answer

Sometimes the dose of the active substance is indicated in relation to 100 ml or 100 mg. The calculations in this case are similar to the previous ones. How to calculate if the dose is given per 100 g of liquid? Example: the annotation states that 100 g of the finished solution contains 40 mg of the active substance. We take into account that 100 g is 20 teaspoons of 5 ml. Now let’s do the calculations: divide the indicated dose of the substance (40 mg) by 20. That is: 40 mg / 20 = 2 mg. Therefore, the dose of the drug in 1 teaspoon of the finished solution is 2 mg

Liquid volume measures

1 teaspoon = 5 ml.

1 dessert spoon = 2 teaspoons = 10 ml.

1 tablespoon = 3 teaspoons = 15 ml.

Composition - 15 mg / 5 ml. (indicated on the package or in the instructions) This means that 1 teaspoon contains 15 mg. medicine.

If you are prescribed a single dose of 15 mg, then you should take 1 teaspoon of syrup at one time.

If you are prescribed a single dose of 30 mg, then you should take 2 teaspoons of syrup at one time.

The bottle contains 80 mg / 160 ml, where 80 mg is the active ingredient. In this case, it is recommended to take the drug 1 teaspoon 2 times a day.

We calculate the dose of 1 ml: for this, the dose of the substance in the entire volume must be divided by the entire volume of liquid:

Divide 80 mg by 160 ml = 0.5 mg per 1 ml.

Since a teaspoon holds 5 ml, we multiply the result by 5. That is: 0.5 mg X 5 = 2.5 mg.

Therefore, 1 teaspoon (single dose) contains 2.5 mg. active substance.

The instructions indicate that 60 ml of the finished solution contains 3000 mg of the active substance.

And 60 ml is 12 teaspoons of 5 ml.

Now let’s do the calculations: the indicated dose of the substance is 3000 mg. divide by 12. That is: 3000 mg / 12 = 250 mg.

This means that 1 teaspoon of the prepared solution is 250 mg.

100 mg. The active substance is contained in 5 ml.

In 1 ml. contains: 100 divided by 5 = 20 mg. active substance.

You need 150 mg.

Divide 150 mg by 20 mg - you get 7.5 ml.

STANDARD DILUTION OF ANTIBIOTICS FOR INTRAMUSCULAR ADMINISTRATION

1 mg = 1000 mcg;

1 mcg = 1/1000 mg;

1000 mg = 1 g;

500 mg = 0.5 g;

100 mg = 0.1 g;

1% corresponds to 10 g/l and 10 mg/ml;

2% 20 g/l or 20 mg/ml;

1:1000 = 1 g/1,000 ml = 1 mg/ml;

1:10,000 = 1 g/10,000 ml = 0.1 mg/ml or 100 µg/ml;

1:1,000,000 = 1 g/1,000,000 ml = 1 μg/ml

If a solvent is not provided in the package, then when diluting the antibiotic by 0.1 g (100,000 units) of powder, take 0.5 ml. solution.

Thus, for breeding:

0.2 g. 1 ml needed. solvent;

0.5 g. You need 2.5-3 ml. solvent;

1 g. need 5 ml. solvent;

A bottle of ampicillin contains 0.5 g of dry medicine. How much solvent do you need to take in 0.5 ml? the solution contained 0.1 g of dry matter.

When diluting the antibiotic by 0.1 g of dry powder, take 0.5 ml. solvent, therefore:

0.1 g of dry matter – 0.5 ml. solvent

0.5 g of dry matter - X ml. solvent

Answer: in 0.5 ml. the solution was 0.1 g of dry matter, you need to take 2.5 ml. solvent.

Often, already five to ten years after leaving school, the knowledge acquired becomes somewhat dim in our memory. Most often this is due to the fact that we do not need to use them in real life. However, if the dates of birth of writers, complex chemical formulas and other specific knowledge are really unlikely to be useful to us in everyday life, it makes sense to refresh some information obtained during our time at school. So, for example, do you remember how many milligrams are in a gram?

We are not asking this out of idle curiosity. Cooking, medicine, and cosmetology often work with small doses of substances. In this case, the result of your efforts directly depends on whether you can correctly convert one value into another: whether you will be able to treat your guests to delicious pastries, correctly calculate the dosage of medicine for a child, or surprise your friends with homemade cosmetics. Therefore, knowledge of how many milligrams per gram is necessary in everyday life.

Gram as a unit of mass

Let's start with what a gram is as a unit of mass. For the first time, the idea that the system of measures needed to be somehow unified was thought about in France back in the 17th century, but work began seriously on the theory of a unified metric system only in 1790. The National Assembly instructed the Academy of Sciences of the French capital to prepare a new system of measures. In 1795, an unchangeable unit of length was established - the meter, which is one forty-millionth of the Paris meridian. After this, scientists Antoine-Laurent de Lavoisier and Rene-Juste Gaüy presented their own developments for determining the weight of water, which were to form the basis of a system for measuring gravity. The very idea of using water to determine the unit of measurement of mass belongs to the British philosopher John Wilkins, who first voiced it back in 1668.

Thus, the concept of a gram was introduced - the weight of one cubic centimeter of pure water at the melting temperature of ice. The official “date of birth” of the gram is April 7, 1795. The Greek word "γράμμα" (gramma) means "small weight".

Since in those days trade dealt mainly with objects whose weight was many times greater than one gram, it became necessary to determine some more significant standard of mass. As a result, it was decided to introduce the concept of a kilogram - the equivalent of the mass of one cubic decimeter of water.

In 1889, during the First International Conference of Weights and Measures, the kilogram standard was presented - you will agree that using water to determine mass is not very convenient. As a result, a cylinder was made from an alloy of platinum and iridium, which is still kept in the Chamber of Weights and Measures. Copies of it are also available in other countries.

So how many milligrams are in a gram?

If everything is more or less clear with grams and kilograms, then the question of how many milligrams in one gram can confuse some. Moreover, there are people who are absolutely convinced that a milligram is a hundredth part of a gram. However, this opinion is wrong.

The prefix “milli-” denotes a thousandth part. In other words, there are a thousand milligrams in one gram. Thus, a milligram is one thousandth (0.001) of a gram.

Sometimes it may be necessary to convert milligrams not only to grams, but also to kilograms.

100 mg how many grams table complete. How many milligrams are in a gram and why you need to know it.

To do this, remember that there are a thousand grams in one kilogram. Considering that there are 1000 mg in 1 gram, we can calculate that there are 1,000,000 milligrams in one kilogram: (1000 mg * 1000 g).

Now let's try to use the acquired knowledge in practice. Sometimes young mothers publish panic messages on thematic forums: the drug is recommended for the child at a dose of 0.25 g, and the tablet weight is 500 mg. Does this mean that you should immediately run to the pharmacy and look for a medicine in a different dosage - or can you use a simple formula and convert one unit to another?

500 mg is 0.5 g (0.001 * 500).

Therefore, a dose of 0.25 g can be obtained by splitting the tablet in half.

Here are a few more multiple units of measurement:

1 mg = 0.001 g;
1 mg = 1000 mcg;
1 mg = 1* 10-8 quintals;
1 mg = 1* 10-9 tons.

More about the kilogram

Kilogram(in Russian notation: kg; in international: kg) is a unit of mass.

How many milligrams are in a gram and why you need to know it

It is one of several (seven) main units of measurement included in the international system of measures.

In 1901, the current concept of the kilogram was set out by the 3rd General Conference on Weights and Measures as follows: the kilogram is a unit of mass that is equal to the mass of the international standard kilogram. The most important sample (standard) of the kilogram is located at the International Bureau of Weights and Measures, located in the city of Sèvres near Paris. This is a cylinder with a height and diameter of about 39.17 millimeters made of a platinum-iridium alloy. It contains 10% iridium and 90% platinum.

At first, a kilogram was defined as the mass of one liter (cubic decimeter) of absolutely pure water at atmospheric pressure at sea level and at a temperature of 4 °C. By coincidence of historical circumstances, the term “kilogram” already includes the decimal prefix “kilo”, because of this, multiples and submultiples are created by combining the designations of the unit of measurement “gram” or standard SI prepositions to the name. In the international system of measures it is subdivisional: 1 gram = 10-3 kg.

Duplicate sample 1 kg, located in the United States of America (USA).

At the current moment in time, the kilogram is a unique unit of the international system of measures, defined using an object made by humanity - a platinum-iridium sample. With the help of basic (fundamental) physical laws and properties, all other units of measurement are now determined. The kilogram was established as the mass of 1 cubic decimeter of water at 4°C when the metric system was introduced in the 18th century. At this temperature, water has the highest density. In 1799, a platinum weight was made, which was used as a sample of a kilogram, but its mass was 0.028 grams greater than the mass of 1 cubic decimeter of water. In 1889, today's sample was made - a cylinder with a diameter and height of 39 millimeters from platinum -iridium alloy.

After those times, it is kept under three hermetically sealed hoods at the International Bureau of Weights and Measures. Specially made exact official copies of the international standard are used as national kilogram samples. In total, more than 80 duplicates were created. Two duplicates of the international standard were transferred to Russia; they are stored at the Mendeleev All-Russian Research Institute of Metrology. About once every ten years, all national duplicates are compared with the international one.

Comparisons indicate that the accuracy of national samples is approximately 2 micrograms. There is no reason to believe that the international standard is more accurate since they are under the same conditions. For various reasons, the international sample loses 3·10-8 of its mass over 100 years. At the same time, based on the concept, the mass of the international standard is exactly equal to one kilogram. That is why all changes in the actual mass of the sample change the unit of measurement “kilogram”. In its Resolution in 1999, the Twenty-First General Conference on Weights and Measures, precisely because of its efforts to correct previously indicated inaccuracies, invited national laboratories to continue efforts to improve the understanding of the relationship of fundamental or atomic constants with units of mass, suggesting a future definition of the kilogram. Over the next decade, a number of international organizations worked to create proposals for redefining the kilogram.

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 number 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 called a gram.

And the problem is solved in a similar way when you need to find out how many milligrams are in it.
We assign three zeros to the number that denotes the amount of g.

1 g x 1000 = 1000 mg, or 1 g = 103 mg. Here is 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 similar arithmetic problems. Most often, this occurs when taking medications.

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

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

But the reverse conversion from milligrams to grams is also often found, especially when preparing food 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 only measure g.

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

How many milligrams are in a gram?

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

The precise definition of a single IU varies for different substances and is established by international agreement. The World Health Organization's Biological Standardization Committee provides reference materials for certain substances, (arbitrarily) specifies the number of IUs they contain, and defines biological procedures for comparing other materials with the standards. The goal of such procedures is to ensure that different preparations having the same biological activity contain equal numbers of IU units.

For some substances, mass equivalents of one IU were eventually established, and measurement in these units was officially abandoned. However, the IU unit may still remain in widespread use due to convenience. For example, vitamin E exists in eight different forms, differing in their biological activity. Instead of accurately indicating the type and mass of the vitamin in the preparation, sometimes it is convenient to simply indicate its quantity in IU.

Wikipedia

International unit (IU)— internationally agreed standards necessary to compare the content of different test biological compounds on the basis of their activity.

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 stored at the State Serum Institute (Copenhagen, Denmark), the National Institute for Health Research (Mill Hill, UK) and the World Health Organization (WHO) (Geneva, Switzerland).

International unit established in the form of a certain 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 21 St Ed.)

How much is 5 milligrams?

What is the difference between 5 mg and 5 ml?

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

To begin with, you need to determine which dosage form in front of us.

Solids are dosed by mass (weighed), and liquids are dosed by volume (measured).

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

Dosing by weight

Weight designations :

1.0 - 1 g (gram)

0.001 - 1 mg (milligram)

0.000001 - 1 mcg (microgram)

Measuring weights, weights, scales (based on the principle of weighing there are: spring, lever, manual, plate 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 talked about dosages in more detail in article.

Dosing by volume

Volume designations:

1 ml - 1 milliliter

1 l - 1 liter

MeasuringTools for the manufacturer: measuring and pharmaceutical pipettes, volumetric flasks, cylinders, beakers, burettes.

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

Let's fix:

What does the designation say? 1,0 ?

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

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

How to calculate the required number of drops?

A 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 the drop depends on the physical properties of the dosed liquid.

For comparison: the volume of 1 drop of an alcohol solution is on average 0.02 ml, while that of an aqueous solution can range from 0.03 to 0.05 ml.

Pharmacists and doctors 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 a drug in drops is prescribed, it is assumed that the volume of one drop is 0.05 ml. If you have a 1 ml medical syringe at home, then you can easily determine the required volume of medicine: 2 drops - 0.1 ml, 3 drops - 0.15 ml, 5 drops - 0.25 ml.

Spoons are also an imprecise measuring device for determining the volume of a dosage form. Volume conventions are also adopted for them.

Reminder when dosing liquid dosage forms:

1 drop (drop) = 0.05 ml

2 drops = 0.1 ml (measured with a 1 ml syringe)

20 drops (pipette) = 1 ml

1 tsp (teaspoon) = 5 ml

1 d.l. (dessert or baby spoon) =10 ml

1 tbsp. (tablespoon) = 15 ml

1 tbsp. (glass) = on average 200 ml (glasses come in different capacities: from 110 to 320 ml)

In one of the following issues, you will learn how to determine the content of the active substance in the dosage form, and how to calculate single/daily doses of the drug.

Be healthy! Treat consciously!

Quick answer: 1 g - 1000 mg.

Whatever you say, we tend to forget some information from school, especially if we never encounter it throughout our lives. For example, do you remember how many milligrams are contained in 1 gram?

How many milligrams are in one gram?

It’s good 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. But we will answer the question.

A milligram is a unit of mass in the International System of Units (SI). 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.

Is it easy to remember?

Quite. However, in practice, we often encounter 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 will simply convert the values. So, 0.25 g is 250 mg. We divide the prescribed 750 mg by 250 mg and get the number 3. Three - that’s exactly how many tablets you need to take.

Of course, you can translate everything back. 750 mg is 0.75 g. A 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 comment 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. To convert grams to milligrams you don’t even need a calculator – just basic knowledge of arithmetic.

Instructions

1. To convert a gram to a milligram, multiply the number of grams by 1000. That is, use the following primitive formula: Kmg = Kg * 1000, where Kmg is the number of milligrams, Kg is the number of grams. So, 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 grams is an integer, then to convert grams to milligrams, simply add three zeros to the right of it. Let's say one tablet of ascorbic acid with glucose weighs 1 gram. This means its mass in milligrams will be: 1,000.

3. If the number of grams is expressed as a decimal, move the decimal point three digits to the right. Let's say the content 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 after the comma, complete the missing characters with zeros. So, say, the table of contents of ascorbic acid in one tablet of ascorbic acid with glucose is 0.1 grams. In milligrams it will be 100 mg (according to the rule, it turns out to be 0100 mg, but insignificant zeros on the left are discarded)..

5. If all the initial data are given in grams, and the result needs to be presented in milligrams, then carry out all intermediate calculations in grams, and convert only the result of the calculations into milligrams. 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. To calculate: how many milligrams of energetic substances are contained in one allochol tablet, add up the masses of all components, expressed in grams, and convert the result to milligrams: 0.08 + 0.04 + 0.005 + 0.025 = 0.15 (g). 0.15 * 1000 = 150 (mg).

Gram is a unit of measurement of mass belonging to the metric system. Gram is one of the main units of the GHS system of unconditional measures (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?

Its multiple unit of measurement of mass kilogram is one of the basic SI units, denoted kg or kg.

Instructions

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

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

Note!
The conversion of grams to milligrams is used mainly in calculations related to the preparation of drugs and their dosage. When making calculations, be very careful - a mistake of one decimal place will lead to a tenfold error.
