The karat (carat in Britain) is used for two things. (1) as the weight of a gem such as a diamond. 1 karat is 0.2 gram (gramme). (2) as the purity of gold. 24 karat gold is 100% gold. 18 karat gold is 75% (18/24) gold. [Gold is combined with silver and/ or copper when not 24 karat]

In dentistry, silver is most often used to make dental fillings. However, since more people are now opting for tooth-colored fillings, silver is not as widely used as it once was.
A karat signifies how pure gold is and the higher the more gold there is. Pure gold, which is 100%, is too soft to use so it often has other metals mixed in to make more durable. 14 karat gold is about 58.5% pure gold, 18 karat gold has 75.0% gold in it and 22k gold has 91.6% gold.
It is used to measure the purity of gold alloys. One karat (or carat) is equal to 1/24 purity by mass.
