Conversion of carats
In order to convert carats [ct] into another weight unit, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large and confusing, making it difficult for inexperienced users to understand. The following tool provides a solution to this problem by allowing the rounded conversion values for carats [ct] to be queried directly from the conversion table.
Determine conversion factor
Conversion between carats and milligrams
A quick and precise conversion between carats [ct] and milligrams [mg] is straightforward and requires only multiplication or division by 200. The conversion from carats [ct] to milligrams [mg] is done by multiplying the value in carats [ct] by 200. To reverse the conversion, divide the value in milligrams [mg] by 200 to obtain carats [ct].
- Milligrams [mg] = carats [ct] * 200
- 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
Carats [ct] and grams [g] can be converted quickly and accurately with just a simple multiplication or division using the conversion factor 5. Converting grams [g] to carats [ct] is performed by multiplying the number of grams [g] by 5. To convert a value from carats [ct] to grams [g], divide the number of carats [ct] by 5.
- Carats [ct] = grams [g] * 5
- Grams [g] = carats [ct] ÷ 5
Conversion between carats and kilograms
A quick and precise conversion between carats [ct] and kilograms [kg] is straightforward and requires only multiplication or division by 5,000. The conversion from kilograms [kg] to carats [ct] is done by multiplying the value in kilograms [kg] by 5,000. To reverse the conversion, divide the value in carats [ct] by 5,000 to obtain kilograms [kg].
- Carats [ct] = kilograms [kg] * 5,000
- Kilograms [kg] = carats [ct] ÷ 5,000
