A microgram is a metric unit of mass that is equal to one thousandth of a milligram (mg). In other words, a microgram is one thousand times smaller than a milligram. Micrograms are a million times smaller than grams (g); one gram is equal to one million micrograms. A microgram is one of the smallest units of mass that is used. Many medications are prescribed using micrograms as their unit of measurement.
Also remember, that mcro, by SI convention means 0.000001, or a millionth (of a gram) and milli means 0.001. 0.001/0.000001 is 0.001. So this means a microgram is 0.001 milligrams, 0.001 milligrams to get this to 1 milligram, you have to multiply by 1000. Therefore you have 1 milligram equals 1000 micrograms.
