Step-by-step example — Convert 1 ct to kg:
A Carat (ct) is a unit of mass equal to exactly 200 milligrams, used almost exclusively for gemstones and pearls.
A Kilogram (kg) is the SI base unit of mass, defined via the Planck constant. It is the standard everyday mass unit almost everywhere outside the US.
The formula is: Kilogram = Carat x 0.0002. Multiply any Carat value by 0.0002 to get the equivalent in Kilogram.
1 ct = 0.0002 kg.
1 kg = 5000 ct.
Carat is smaller than Kilogram. 1 Kilogram = 5000 ct.
5 ct = 0.001 kg.
70 kg = 350,000 ct.
No — carat (ct) measures the weight of a gemstone, while karat (kt) measures gold purity out of 24 parts. The different spelling helps tell them apart.
