The grain (gr) is exactly 64.79891 milligrams and is the base of the avoirdupois, troy and apothecaries weight systems, originally based on a grain of barley. It is used today mostly for the weight of bullets and powder charges in ammunition.
The metric carat (ct) is exactly 200 milligrams and is the unit for weighing gemstones such as diamonds. It should not be confused with the karat, which measures the purity of gold.
