During the work with small amounts of substance such unit of measure of weight as milligram (mg) is often used. Milligram is called the thousand share of gram. that is, one gram contains one thousand milligrams. To transfer grams to milligrams even the calculator – enough elementary knowledge of arithmetics is not required.
Instruction
1. To transfer gram to milligram, increase the number of grams by one thousand. That is use the following simple formula: Kmg = Kg * 1000, gdekmg – the number of milligrams, Kg – the number of grams. So, for example, the mass of one tablet of activated carbon – 0.25 grams. Therefore, its weight expressed in milligrams will be: 0.25*1000=250 (mg).
2. If the number of grams – an integer, then for transfer of grams to milligrams just attribute to it three zero on the right. For example, one tablet of ascorbic acid with glucose weighs 1 gram. Means, its weight in milligrams will be: 1,000.
3. If the number of grams is expressed in the form of decimal fraction, then transfer a decimal point to three figures to the right. For example, contents glucose in one tablet of ascorbic acid with glucose – 0.887 grams. Therefore, in milligrams the mass of glucose will be 887 mg.
4. If after a comma it is less than three figures, add missing signs with zero. So, for example, the content of ascorbic acid in one tablet of ascorbic acid with glucose – 0.1 grams. In milligrams it will be – 100 mg (according to the rule, 0100 mg turn out, but non-significant zero are rejected at the left).
5. If all basic data are set in grams, and the result needs to be presented in milligrams, then carry out all intermediate calculations in grams, and milligrams translate only a result of calculations. So, for example, contains in one: - bile dry – 0.08 g, - garlic dried – 0.04 g, - nettles leaves – 0.005 g, - the coal activated – 0.025 g. To calculate: how many milligrams of active agents contain in one tablet of an allokhol, put the mass of all a component expressed in grams, and transfer result to milligrams: 0.08+0.04+0.005+0.025=0.15 (g).0.15*1000=150 (mg).
