Kilogram (kg) — the SI base unit of mass
It is defined by fixing the Planck constant at exactly 6.62607015×10⁻³⁴ J·s; together with the definitions of the meter and second, this sets the kilogram. Used worldwide for measuring mass in science, engineering, commerce, medicine, food, shipping, and everyday life.
- Symbol: kg
- System: SI base unit for mass
- Exact relations: 1 kg = 1000 g = 1,000,000 mg
- Imperial equivalents (derived from 1 lb = 0.45359237 kg exactly): 1 kg ≈ 2.20462 lb ≈ 35.27396 oz
- Typical examples: 1 liter of water ~1 kg; a laptop ~1.5 kg; an adult person ~70 kg.
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.
