We remember the school curriculum – how many milligrams are in a gram

how many milligrams in gram We often forget that we went to school and took a course in physical quantities and their units of measurement. Many do not even know: how many milligrams are in a gram, and vice versa.

Why is it so important?

Let’s, for a start, figure it out: where it is necessary to know (without fail), and how knowledge about grams and milligrams can someday come in handy in the life of each of us.

Medicine and industry

the pharmacist knows how many milligrams are in a gram This knowledge is simply indispensable when it comes to medical dosages, industrial and cosmetic proportions. Moreover, if we talk about medicine, then there is no way to be frivolous about values. After all, the lives of millions of people depend on this! The same is true in industry where precision is important. Imagine if an employee of an arms factory did not know how many milligrams there are in one gram of gunpowder. It’s scary to even speculate about what can happen due to the lack of knowledge about grams and milligrams..

In medicine, due to an error in the proportions of active substances, a medicine can become a deadly poison, even if half a milligram is superfluous or insufficient.!

precision industryUnfortunately, there are more and more modern people who do not even have the concept of converting (translating) physical quantities. Probably, it is no longer a secret that such people can and have already ended up in the medical or industrial sphere, where one cannot do without it. There are also those who confidently say: “There are one hundred milligrams in one gram.” This applies not only to mass, but also to knowledge about other quantities. And who knows where they work? Such mistakes are fraught with accidents and disasters..

In SI, only kilograms are used for calculations. Even a small amount of mass is converted into kg. For example, 123 grams should be written as 0.123 kg.

Thanks to those people who are fluent in translations of units of measurement of physical quantities, we are alive and have the opportunity to heal diseases, use other substances to make our own life easier. Pharmacists, for example, know how to dose drugs correctly. Chemists who develop pesticides and fertilizers receive effective preparations so that the harvest is good and pests do not destroy crops. They, like no one else, know: how many mg are in 1 gram.

Life situations

Probably, you have often heard from children who go to school, for example, the following words: “Why should I know this? I will be a policeman, and this will not be useful to me in my life! ” In fact, it comes in handy.

we calculate the dosage of the medicine correctlyLet’s say you have to give an old grandmother a medicine. The instructions say that you need to take 250 mg twice a day. 250, no more and no less! Otherwise, the drug will begin to act incorrectly, cause side effects, or even an overdose. On the box with tablets there is an inscription: “The package contains 50 tablets of 1 g of active substance”. In the instructions, they do not write that it is necessary to break the pill into exactly four parts, but they write that you should take 250 milligrams each. As you can see, you need to know: how many milligrams are in one gram.

Or, cases with fertilizers, which are sometimes packaged in several grams. For example, a sachet contains one gram of powder. To fertilize, say, an indoor flower, you need to dilute 500 milligrams in 200 milliliters of water. Again, they did not write that the half of the sachet should be diluted, namely 500 mg.

Hunting, the same case with gunpowder. Let’s come up with a situation. A person does not buy ready-made cartridges, but loads them on his own. Takes a kilogram of gunpowder. You need to pour into the cartridge, for example, 2.25 g. It has an accurate scale that shows only in milligrams. He sits and thinks: “What should a milligram scale show me so that I would fall asleep in a cartridge of 2.25 grams?” It would be appropriate to know that the required mass of gunpowder should be 2250 milligrams on its scales. Of course, you can use special programs.program for accurate calculations

Such cases can be cited as examples endlessly. There is only one conclusion from this: whether you work in the precision industry or not, you should have knowledge of units of measurement in your head. Will come in handy anyway.

How to calculate

mass unitsNow let’s figure it out: how many mg are in 1 gram and vice versa. First of all, it is worth remembering that there are 1000 milligrams in one gram. And 1 milligram is one thousandth of a gram. That is, 1 mg is 0.001 g and 1 g is 1000 mg.

The main thing is not to be mistaken with zeros and correctly carry the comma of decimal fractions:

  • 1 gram = 1000 milligrams;
  • 10 grams = 10,000 milligrams;
  • 5 milligrams = 0.005 grams;
  • 50 milligrams = 0.05 grams;
  • 500 milligrams = 0.5 (half) grams.

Now we know how many milligrams 1 gram is. And if on the contrary, then you need to deal with decimal fractions. One zero is one decimal place transfer. If we want to write 1 milligram in the form of grams, then we get 0.001.

1 milligram is one thousandth of a gram. We divide 1 by a thousand, that is, we transfer the comma to the left by three digits, since there are three zeros in a thousand. 10 milligrams is one hundredth of a gram (for two digits). 100 milligrams – one tenth (one digit).

For example, you have 24 milligrams. In grams, it looks like this: 0.024 g. 24 divided by a thousand. If from grams to milligrams, then zeros are added accordingly. 356 grams is 356,000 mg.

Easier to work with comma hyphenation. It’s faster this way and you can never go wrong.
