gr

unit of weight equal to 0.065 gram, or 17,000 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. The ancient grain, varying from one culture to the next, was defined as the weight of a designated number of dry wheat (or other edible grain) kernels taken from the middle of the ear. It was also used as the original basis for the medieval English inch, which was defined for instructional purposes as the length of 3 medium-sized barleycorns placed end to end (about 2.54 cm). The Sumerian shekel equaled the weight of 180 wheat grains; the British silver penny sterling was set at the weight of 32 wheat grains. The metric grain of 50 mg is used to weigh precious stones.
