- grain
(gr)
1. a traditional unit of weight. The grain, equal to 1/480 troy
ounce (see also
pound2), or exactly 64.798 91 milligrams, was the legal foundation of traditional English weight systems, with various pounds being defined as a specified number of grains: 5760 grains in a troy pound and 7000 grains in an avoirdupois pound, for example. In the version of the troy system used by jewelers, there are 24 grains in a
pennyweight and 20 pennyweight in an ounce. In the version used by apothecaries, there are 20 grains in a
scruple, 3 scruples in a
dram, and 8 drams in an ounce. Originally the grain was defined in England as the weight of a barleycorn. This made the English grain larger than the corresponding grain units of France and other nations of the Continent, because those units were based on the weight of the smaller wheat grain.
2. a unit of weight formerly used by jewelers in measuring diamonds and other precious stones. The jeweler's grain is exactly 1/4
carat. Now that the carat has been standardized at 200 milligrams, the jeweler's grain is exactly 50 milligrams, or approximately 0.7716 troy grain. This unit is widely used for measuring pearls, so it is sometimes called the
pearl grain.
3. a traditional French unit of weight equal to 53.115 milligrams.
