This calculator requires a Javascript-enabled browser. This calculates the weight, grams, and kilograms of conversion between grams and carats. Carat, referred to as "CT". Spelled with "c", is the weight unit used for the gemstone. The carat weight was standardized in the 20th century. The United States officially passed the metric carat in 1913. One carat = 0.2 g (200 mg). Measure one hundred carats of stone. One-third of a carat is also called a point. Therefore, a 0.10 carat diamond can be called 10 points, or 1/10 carats. Small stones like 0.05, .10 carats are the most frequently mentioned point codes. The purity of the carat gold alloy spelled with "K" is measured, not stone. The average ratio of round diamonds of one carat is about 6.5 mm in diameter. Be aware that this unique weight and volume relationship is different from the stone. Gems such as rubies and sapphires are heavier than diamonds. Technically, they have a higher specific gravity, so a 1-carat ruby or sapphire is smaller than a one-carat diamond.
