How to Convert Short Ton to Metric Ton
- 1 ton (US) = 0.90718474 t
- 1 t = 1.102311311 ton (US)
- Example: convert 15 ton (US) to t: 15 ton (US) = 15 × 0.90718474 t = 13.6077711 t
Reference conditions. ton (US): Avoirdupois system: 1 lb = 16 oz = 7000 grains = 0.45359237 kg exactly (1959 agreement).
Formula
t = ton (US) × 0.90718474
or t = ton (US) ÷ 1.102311310924
Derivation from SI units:
- 1 short ton = 2000 lb = 907.18474 kg (exact)
- 1 t = 1000 kg (accepted for use with the SI)
- 1 ton (US) = 907.18474 kg ÷ 1000 kg per t = 0.90718474 t
Both units are defined exactly, so the factor is exact. Short Ton definition: short ton; Metric Ton definition: metric ton.
Worked examples
- A reading of 3 ton (US) converts to 2.72155422 t.
3 ton (US) × 0.90718474 = 2.72155422 t - A value of 40 ton (US) is 36.2873896 t.
40 ton (US) × 0.90718474 = 36.2873896 t
