How to Convert Ounce to Short Ton
- 1 oz = 0.00003125 ton (US)
- 1 ton (US) = 32000 oz
- Example: convert 15 oz to ton (US): 15 oz = 15 × 0.00003125 ton (US) = 0.00046875 ton (US)
Reference conditions. oz: 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) = oz ÷ 32000
Derivation from SI units:
- 1 oz = 1/16 lb = 28.349523125 g (exact)
- 1 short ton = 2000 lb = 907.18474 kg (exact)
- 1 oz = 0.028349523125 kg ÷ 907.18474 kg per ton (US) = 0.00003125 ton (US)
Both units are defined exactly, so the factor is exact. Ounce definition: ounce; Short Ton definition: short ton.
Worked examples
- A reading of 4 oz converts to 0.000125 ton (US).
4 oz × 0.00003125 = 0.000125 ton (US) - A value of 12 oz is 0.000375 ton (US).
12 oz × 0.00003125 = 0.000375 ton (US)
