Definition of the Carat
The carat is defined as 200 milligrams, which is one fifth of a gram. The carat is divided into 100 points, which are each 2 milligrams. For example, a diamond that weighs 0.5 carat can also be expressed as 50 points or 100 milligrams.
The carat is not a legal unit of measurement in most countries, except for some that use the metric system, such as France, Belgium, Italy and Switzerland. In other countries, such as the United States, Canada, Australia and New Zealand, the carat is used as a standard unit for the diamond industry.
How to Convert Carats
Carats can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert carats to other units of weight in the US customary system and the SI system:
- To convert carats to ounces, divide by 141.7476. For example, 10 ct = 10 / 141.7476 = 0.071 oz.
- To convert carats to pounds, divide by 2267.962. For example, 20 ct = 20 / 2267.962 = 0.009 lb.
- To convert carats to tons (short), divide by 4535923.7. For example, 50 ct = 50 / 4535923.7 = 0.000011 ton.
- To convert carats to grams, divide by 5. For example, 100 ct = 100 / 5 = 20 g.
- To convert carats to kilograms, divide by 5000. For example, 200 ct = 200 / 5000 = 0.04 kg.
- To convert carats to milligrams, multiply by 200. For example, 25 ct = 25 x 200 = 5000 mg.
