| troy | <unit> Troy weight, the weight which gold and silver, jewels, and the like, are weighed. It was so named from Troyes, in France, where it was first adopted in Europe. The troy ounce is supposed to have been brought from Cairo during the crusades. In this weight the pound is divided into 12 ounces, the ounce into 20 pennyweights, and the pennyweight into 24 grains; hence, the troy ounce contains 480 grains, and the troy pound contains 5760 grains. The avoirdupois pound contains 7000 troy grains; so that 175 pounds troy equal 144 pounds avoirdupois, or 1 pound troy = 0.82286 of a pound avoirdupois, and 1 ounce troy = 1 17/175 or 1.09714 ounce avoirdupois. Troy weight when divided, the pound into 12 ounces, the ounce into 8 drams, the dram into 3 scruples, and the scruple into 20 grains, is called apothecaries' weight, used in weighing medicines, etc. In the standard weights of the United States, the troy ounce is divided decimally down to the 1/10000 part.

The pound troy is divided into twelve ounces, and contains 5,760 grains. 144 pounds avoirdupois are equal to 175 pounds troy weight. See Avoirdupois, and Troy. 2. A British denomination of money of account, equivalent to twenty shillings sterling, and equal in value to about $4.86. There is no coin known by this name, but the gold sovereign is of the same value. The pound sterling was in Saxon times, about A. D. 671, a pound troy of silver, and a shilling was its twentieth part; consequently the latter was three times as large as it is at present. Source: Websters Dictionary (01 Mar 1998) |
