How to Convert Stone to Short Ton
- 1 st = 0.007 ton (US)
- 1 ton (US) = 142.8571429 st
- Example: convert 15 st to ton (US): 15 st = 15 × 0.007 ton (US) = 0.105 ton (US)
Reference conditions. st: 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) = st × 0.007
or ton (US) = st ÷ 142.8571428571
Derivation from SI units:
- 1 st = 14 lb = 6.35029318 kg (exact)
- 1 short ton = 2000 lb = 907.18474 kg (exact)
- 1 st = 6.35029318 kg ÷ 907.18474 kg per ton (US) = 0.007 ton (US)
Both units are defined exactly, so the factor is exact. Stone definition: stone; Short Ton definition: short ton.
Worked examples
- A reading of 10 st converts to 0.07 ton (US).
10 st × 0.007 = 0.07 ton (US) - A value of 14 st is 0.098 ton (US).
14 st × 0.007 = 0.098 ton (US)
