Long ton (UK ton) — an imperial unit of mass equal to 2240 pounds
It is defined as exactly 2240 avoirdupois pounds; since 1 lb = 0.45359237 kg exactly, 1 long ton = 1016.0469088 kg exactly. Used mainly in the United Kingdom and some Commonwealth contexts for measuring large masses in shipping, industry, freight, and historical trade.
- Symbol: long ton, UK ton
- System: Imperial unit for mass
- Exact relations: 1 long ton = 2240 lb = 35,840 oz = 1016.0469088 kg
- Metric equivalents: 1 long ton ≈ 1016.05 kg ≈ 1.01605 t
- Typical examples: ship displacement may be measured in long tons; heavy freight can be listed in long tons; 1 long ton is slightly heavier than a metric ton.
Milligram (mg) — a small SI unit of mass
It is defined as one thousandth of a gram, or one millionth of a kilogram, the SI base unit for mass. Used worldwide for measuring very small masses in medicine, nutrition, chemistry, laboratory work, supplements, and precise product labeling.
- Symbol: mg
- System: SI unit for mass; decimal submultiple of the kilogram
- Exact relations: 1 mg = 0.001 g = 0.000001 kg = 1000 µg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 mg ≈ 0.000035274 oz ≈ 0.00000220462 lb
- Typical examples: a medicine dose ~200 mg; a vitamin tablet ~500 mg; a small grain of salt less than 1 mg.
