To convert grams to milligrams, multiply the number of grams per thousand.That is, use the following simple formula:
KG = EP * 1000 where
KMG - the number of milligrams,

KG - the number of grams.
For example, the weight of one tablet of activated charcoal - 0.25 grams.Consequently, its weight, expressed in milligrams will be 0.25 x 1000 = 250 (mg).
If the number of grams - an integer, then to translate grams into milligrams simply ascribe it to the right of three zeros.
example, one tablet of ascorbic acid with glucose weighs one gram.So its mass in milligrams will be 1 000.
If the number of grams is expressed in the form of a decimal fraction, then move the decimal point three digi
ts to the right.
example, a glucose tablet ascorbic acid with glucose - 0.887 grams.Consequently, the mass in milligrams of glucose will be 887 mg.
If the comma is less than three digits, add zeros missing signs.

For example, the content of ascorbic acid per tablet ascorbic acid, glucose - 0.1 gram.It will be in milligrams - (100 mg, according to the rules, it turns out 0100 mg, but the zeros on the left are discarded) ..
If all inputs are given in grams and the result must be submitted in milligrams, then all intermediateCalculations were carried out in grams and milligrams move only up calculations.
For example, in one tablet contains allohol:

- bile dried - 0.08 g,

- dried garlic - 0.04 g,

- nettle leaves - 0.005 g,

- activated carbon - 0.025 g.

To calculate how many milligrams of the active substances contained in one pill allohol, add the weight of all components expressed in grams, and the result in milligrams translate:

0,08 + 0,04 + 0,005 + 0,025 = 0,15 (Mr.).

0.15 * 1000 = 150 (mg).
