A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly 64.798 91 milligrams. It is nominally based upon the mass of a single ideal seed of a cereal.

grain, unit of weight equal to 0.065 gram, or 1 / 7,000 pound avoirdupois. One of the earliest units of common measure and the smallest, it is a uniform unit in the avoirdupois, apothecaries’, and troy systems.
