Microgram (µg) — a very small SI unit of mass
It is defined as one millionth of a gram, or one billionth of a kilogram, the SI base unit for mass. Used worldwide for measuring extremely small masses in medicine, nutrition, chemistry, toxicology, laboratory analysis, and trace substances.
- Symbol: µg
- System: SI unit for mass; decimal submultiple of the kilogram
- Exact relations: 1 µg = 0.001 mg = 0.000001 g = 0.000000001 kg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 µg ≈ 0.000000035274 oz ≈ 0.00000000220462 lb
- Typical examples: a vitamin B12 dose ~500 µg; a folic acid tablet ~400 µg; trace contaminants in food or water often measured in µg.
