How do you convert micrograms to milligrams?

Answer by  MathGeek77 (19)

A microgram is 1/1000 of a milligram, so to convert micrograms to millgrams, divide by 1000. To convert the other way, multiply millgrams by 1000 to get micrograms. For example, if something weighs 100 milligrams, it is 100/1000 or 1/10th of a milligram. If you have 10 milligrams, that is 10,000 micrograms.
