A microgram is a metric unit of mass equal to one millionth of a gram (0.000001 g) or one billionth of a kilogram. The microgram (sometimes abbreviated 'mcg' in medicine to avoid confusion with 'mg') became important with the discovery of vitamins and hormones that are active in tiny quantities. The prefix 'micro' comes from the Greek for 'small'.

Common uses of micrograms include: Vitamin and trace-mineral dosages (e.g. vitamin D, B12); Hormone and potent drug amounts; Environmental contaminant concentrations; Analytical chemistry and toxicology.
