How to Convert Long Ton to Short Ton
- 1 ton (UK) = 1.12 ton (US)
- 1 ton (US) = 0.8928571429 ton (UK)
- Example: convert 15 ton (UK) to ton (US): 15 ton (UK) = 15 × 1.12 ton (US) = 16.8 ton (US)
Reference conditions. ton (UK): Avoirdupois system: 1 lb = 16 oz = 7000 grains = 0.45359237 kg exactly (1959 agreement). ton (US): Avoirdupois system: 1 lb = 16 oz = 7000 grains = 0.45359237 kg exactly (1959 agreement).
Formula
ton (US) = ton (UK) × 1.12
Derivation from SI units:
- 1 long ton = 2240 lb = 1016.0469088 kg (exact)
- 1 short ton = 2000 lb = 907.18474 kg (exact)
- 1 ton (UK) = 1016.0469088 kg ÷ 907.18474 kg per ton (US) = 1.12 ton (US)
Both units are defined exactly, so the factor is exact. Long Ton definition: long ton; Short Ton definition: short ton.
Worked examples
- A reading of 5 ton (UK) converts to 5.6 ton (US).
5 ton (UK) × 1.12 = 5.6 ton (US) - A value of 100 ton (UK) is 112 ton (US).
100 ton (UK) × 1.12 = 112 ton (US)
