  • Carats [ct] = milligrams [mg] ÷ 200

Conversion between carats and centigrams

Conversions between carats [ct] and centigrams [cg] are straightforward and can be performed with simple math. The required conversion factor is 20. To convert a value from carats [ct] to centigrams [cg], multiply the number of carats [ct] by 20. For values in centigrams [cg], divide by 20 to get the equivalent in carats [ct].

  • Centigrams [cg] = carats [ct] * 20
  • Carats [ct] = centigrams [cg] ÷ 20

Conversion between carats and decigrams

The conversion between carats [ct] and decigrams [dg] is quick to perform and requires only basic mathematical operations an the conversion factor 2. Multiply the number of carats [ct] by 2 to get the converted value in decigrams [dg]. To convert a value in decigrams [dg] back to carats [ct], simply divide the amount of decigrams [dg] by 2.

  • Decigrams [dg] = carats [ct] * 2
  • Carats [ct] = decigrams [dg] ÷ 2

Conversion between carats and grams
