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.
Troy ounce (ozt) — a troy unit of mass for precious metals
It is defined as exactly 480 grains, or one twelfth of a troy pound; since 1 grain = 64.79891 mg exactly, 1 troy ounce = 31.1034768 g exactly. Used mainly for measuring precious metals such as gold, silver, platinum, and palladium, as well as bullion and coin weights.
- Symbol: ozt, oz t
- System: Troy unit for mass
- Exact relations: 1 ozt = 480 gr = 20 dwt = 31.1034768 g
- Metric equivalents: 1 ozt = 31.1034768 g ≈ 0.0311035 kg
- Typical examples: a standard gold bullion coin ~1 ozt; silver rounds are often 1 ozt; precious-metal prices are commonly quoted per troy ounce.
