The most essential challenge here is determining how to convert between mg and mcg as well as determining the difference between the two. In addition, according to the metric system, a microgram is a unit of mass measurement. A microgram is one millionth (1106) of a gram, hence it is a unit of measurement for mass. In the International System of Units, this level of measurement is denoted by the letter g. (SI system).

In addition, the notation mcg is often used in American medical discourse rather than mg as the shorthand for micrograms. The letter g contains the Greek letter that is used as the prefix sign for the word “micro” (Mu).
The quantity of milligrams that are equal to one microgram (g) is one thousand (mg).
m(μg) = m(mg) × 1000
The unit of mass known as a milligram (mg) is equivalent to one thousand micrograms (g) (mg).
1 mg = 1000 μg
1 µg = 1×10−3 g
The following table illustrates how to convert 4 milligrams to micrograms.
m(μg) = 4 mg × 1000 = 4000 μg
