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.
Short ton (US ton) — a US customary unit of mass equal to 2000 pounds
It is defined as exactly 2000 avoirdupois pounds; since 1 lb = 0.45359237 kg exactly, 1 short ton = 907.18474 kg exactly. Used mainly in the United States for measuring large masses in freight, shipping, industry, agriculture, construction, vehicles, and commodities.
- Symbol: US ton, short ton
- System: US customary unit for mass
- Exact relations: 1 short ton = 2000 lb = 32,000 oz = 907.18474 kg
- Metric equivalents: 1 short ton ≈ 907.185 kg ≈ 0.907185 t
- Typical examples: a small car ~1.5 short tons; a pickup truck ~2.5 short tons; bulk gravel, coal, or grain often measured in short tons.
