How to Convert Kilogram to Carat
- 1 kg = 5000 ct
- 1 ct = 0.0002 kg
- Example: convert 15 kg to ct: 15 kg = 15 × 5000 ct = 75000 ct
Formula
ct = kg × 5000
Derivation from SI units:
- SI base unit, fixed by the Planck constant h = 6.626 070 15 × 10⁻³⁴ J·s
- 1 ct = 200 mg (metric carat, exact)
Both units are defined exactly, so the factor is exact. Kilogram definition: kilogram; Carat definition: carat.
Worked examples
- A reading of 10 kg converts to 50000 ct.
10 kg × 5000 = 50000 ct - A value of 60 kg is 300000 ct.
60 kg × 5000 = 300000 ct
