Grain
The weight of a single grain of wheat was taken as the smallest unit of weight in England. The troy grain was 1/5760 of a pound, while the avoirdupois grain was 1/7000 pound, the former being used in the weighing of precious metals and thus employed by numismatists in weighing coins. A grain is 1/480 troy ounce or 0.066 gram in the metric system.
