How to Convert Troy Ounce to Metric Ton
- 1 oz t = 0.0000311034768 t
- 1 t = 32150.74657 oz t
- Example: convert 15 oz t to t: 15 oz t = 15 × 0.0000311034768 t = 0.000466552152 t
Formula
t = oz t × 0.0000311034768
or t = oz t ÷ 32150.74656863
Derivation from SI units:
- 1 oz t = 480 gr = 31.1034768 g (exact)
- 1 t = 1000 kg (accepted for use with the SI)
- 1 oz t = 0.0311034768 kg ÷ 1000 kg per t = 0.0000311034768 t
Both units are defined exactly, so the factor is exact. Troy Ounce definition: troy ounce; Metric Ton definition: metric ton.
Worked examples
- A reading of 2 oz t converts to 0.0000622069536 t.
2 oz t × 0.0000311034768 = 0.0000622069536 t - A value of 32.15 oz t is 0.0009999767791 t.
32.15 oz t × 0.0000311034768 = 0.0009999767791 t
