Step-by-step example — Convert 1 ct to mg:
A Carat (ct) is a unit of mass equal to exactly 200 milligrams, used almost exclusively for gemstones and pearls.
A Milligram (mg) is one-thousandth of a gram, a very small unit reserved for precise, low-mass measurements.
The formula is: Milligram = Carat x 200. Multiply any Carat value by 200 to get the equivalent in Milligram.
1 ct = 200 mg.
1 mg = 0.005 ct.
Carat is bigger than Milligram. 1 Carat = 200 mg.
5 ct = 1,000 mg.
250 mg = 1.25 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.
