A unit of mass where 1 microgram equals 10⁻⁶ grams or 0.001 milligrams. Commonly used for pharmaceutical dosages (e.g., daily vitamin D recommendation of 400 mcg) and environmental pollutant concentrations (e.g., heavy metals in PM2.5). Widely used in Chinese drug labels and lab reports; the symbol “μg” is more standard, but “mcg” is often used in medical contexts to avoid printing ambiguities.
