Trow"sers (?), n. pl. Same as Trousers.
Troy (?), n. Troy weight.
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 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 part.
Troy"ounce (?), n. See Troy ounce, under Troy weight, above, and under

Tru"age (?), n. [Cf. OF. truage a tax. See True.] 1. A pledge of truth
