How to Convert Metric Ton to Carat
- 1 t = 5000000 ct
- 1 ct = 2 × 10⁻⁷ t
- Example: convert 15 t to ct: 15 t = 15 × 5000000 ct = 75000000 ct
Formula
ct = t × 5000000
Derivation from SI units:
- 1 t = 1000 kg (accepted for use with the SI)
- 1 ct = 200 mg (metric carat, exact)
- 1 t = 1000 kg ÷ 0.0002 kg per ct = 5000000 ct
Both units are defined exactly, so the factor is exact. Metric Ton definition: metric ton; Carat definition: carat.
Worked examples
- A reading of 3 t converts to 15000000 ct.
3 t × 5000000 = 15000000 ct - A value of 25 t is 125000000 ct.
25 t × 5000000 = 125000000 ct
