What does µg mean?
This entry was posted on November 16, 2020.
µg or (ug or mcg as it is quite often written) is the correct symbol for the metric measurement of microgram. It is one thousandth of a milligram or one millionth of a gram.
Take this as an example:
1g = 1000mg = 1000000µg
Or consider this, moving the decimal place:
1µg = 0.001mg = 0.000001g (also can be written as 1e-6)
µ is actually a symbol for the Greek letter (mu) that means small.
Due to there not being Greek symbols in English typography most of the time. As in our keyboards do not have this symbol, there are two commonly accepted forms of this symbol and they are: ug and mcg.
