About the Units
The carat (ct) is the standard unit of mass for gemstones and pearls, defined as exactly 200 milligrams (0.2 grams). The kilogram (kg) is the base unit of mass in the International System of Units. Because carats are used for tiny objects, you need 5,000 carats to equal a single kilogram.
