One milligram is equal to how many grams?

Explanation:
Metric prefixes scale by powers of ten, and milli means one thousandth. So a milligram is one thousandth of a gram, which is 0.001 grams. In other words, 1 mg = 0.001 g. There are 1000 milligrams in a gram, so to convert mg to g you divide by 1000, and to convert g to mg you multiply by 1000. For perspective, 0.1 g is 100 mg, 0.01 g is 10 mg, and 0.0001 g is 0.1 mg. The value 0.001 g matches 1 mg.
