Definition: The milligram is a metric mass unit for extremely small quantities. There are 1,000 mg in one gram, so each milligram equals 0.001 g.

Current use: Mg appears most often on nutrition labels, supplement facts, preservative amounts, caffeine listings, salt or sodium values, and food-science formulas.
