mg

word

Definition

'mg' is an abbreviation for milligram, a unit of mass equal to one thousandth of a gram. It is commonly used in medicine, nutrition, and science.

Usage & Nuances

Always written in lower-case as 'mg' after a number (e.g., 500 mg). Used almost exclusively for measuring very small quantities, especially of medicine or supplements. Not pronounced as a word, but as 'milligram(s)' in speech. Do not confuse with 'mg' as a chemical symbol, which does not exist; the chemical symbol for magnesium is 'Mg' (capital M).
