How many milligrams in one gram: simple answers to questions

At the end of schooling, many of us forget a lot of the material we've covered. And the simple question - "How many milligrams per gram" - often puzzles, the answer is not clear. Nevertheless, these useful knowledge is very necessary in our daily life! And I'll prove it on the basic everyday examples.

Here, see, the correct dosage of the various ingredients or ingredients in cooking, cosmetology, medicine depends entirely on how diligently we have learned the systems of transfer of body weight from kilograms to grams, and from gram to milligrams.

Frivolous and unfair attitude to any production process will ruin the final result - obtaining a quality product in all respects, whether it be rejuvenating cream, homemade dish or medicine.

We must first understand - what, where and in what quantity can be added. Therefore, knowing how many milligrams per gram in life we ​​are very useful.

How many milligrams are there in one gram?

In working with substances that are small in volume, the smallest quantities of the components are used most often. It is very important not to confuse the ratio of the constituents of the substances.

You know, even on the vastness of the world information web - the Internet, you can sometimes meet "brilliant" knowledge of the physical properties of matter, where "experts" claim that one gram contains 100 milligrams!

But imagine, when people read such posts, some of them are deluded and mistaken in their calculations, do not give and do not bring Lord, if he is a pharmacist!

So, how many grammes are milligrams, how to make calculations correctly?

Remember that one milligram is one thousandth of a gram. The prefix "Milli" means 10 in - 3( minus the third) degree. He points to one thousandth of a share.

One gram consists of one thousand milligrams. Everything is very simple and without a calculator. It is enough to use the most elementary knowledge in the field of arithmetic, well, physics.

Calculations, formula, examples how to calculate

To make it easier to understand how much in 1 gram of milligram, look at a clear example:


1 gram is 1,000 milligrams of

Or on the contrary:

1 milligram will be 0, 001 gram

It follows:

1kilogram will be 1000 grams, this equals 1,000,000 milligrams

With this simple table you can correctly calculate the amount of substances.

If you are going to do the correct cosmetic products, medicines, strictly follow the recipes for their preparation, the knowledge of how many milligrams in one gram is very necessary!

You can independently understand all the nuances and subtleties of culinary or pharmaceutical art, but ignorance of a simple thing, how many milligrams per gram will put a very big question for your professional and amateur suitability in these fields of activity. You must correctly calculate the weight of components and ingredients, quickly find rational solutions.


Let's assume that you really need to give an effective medicine to a small child. Dosage of all drugs is strictly different for an adult and children. The most difficult task is to correctly select the dose of the medicine in order to avoid side effects to children under three years old, very small. Knowing the standard weight of the whole tablet, the amount of active substances in it, you can simply calculate the remedy for crumbs.

For example, the weight of the whole tablet is 500 mg( half one gram).The children's dose of the drug is 0.25 grams. For calculation, we use the elementary school formula, you can use two ways of transferring the values ​​- from gram to milligram, or vice versa. Here is the result:

500 mg = 0.5 grams. And you need only 0.25.Therefore, we divide the pill into two equal parts and get the necessary dose of the medicine.

You can do the opposite:

0.25 grams = 250 milligrams!

As a result, two figures are calculated - 500 milligrams and 250 milligrams. Now it is easier to understand how to properly separate the tablet.

I give you some more examples of translating grams into milligrams and vice versa.

  1. 0.12 grams = 120 milligrams.
  2. 540 milligrams = 0.54 grams.
  3. 0.03 grams = 30 milligrams.
  4. 36 milligrams = 0.036 grams.

Thus, you can simply figure out the incomprehensible values. There is no need to divide or multiply, if we correctly understand the number of zeros.

In the previous version( 2) with 540 milligrams, 0.54 grams can be obtained by moving the separating comma three digits forward, which means three zeros in 1000. Do you remember, did not forget that in one gram 1000 milligrams? And in the example( 3) with a translation of 0.03 grams per milligram, the comma moves three digits back and adds the missing notch. Here is an example: 0.030 = 30.
