The conversion of carats to grams is an important aspect in the world of gemstones and the jewelry trade. However, it is important to note that the term 'carat' is used differently in this context than in relation to the purity of gold.

A carat (ct) is a unit of measurement for the weight of gemstones and pearls. One carat corresponds to 0.2 grams or 200 milligrams. This is an international standard that was introduced in 1907 at the Fourth General Conference on Weights and Measures.

So to convert the weight of a gemstone from carats to grams, simply multiply the number of carats by 0.2. For example, a 5 carat diamond would weigh 1 gram (5 carats * 0.2 g/carat = 1 g).

However, in terms of gold, 'carat' is a unit of measurement for the purity of the gold, not its weight. 24 carat gold is pure gold, while 18 carat gold means that 18 parts of 24 parts are gold, the rest are other metals. It is important to understand this distinction to avoid confusion.
