Domestic Encyclopædia (1802)/Troy-Weight

TROY-WEIGHT, is that mode of weighing certain commodities, in which the pound contains twelve ounces, each of them being divided into twenty penny-weights, and the latter into twenty-four grains each: on the contrary, a pound of avoirdupois consists of sixteen ounces; so that each oz. has eight drams, or drachms; each dram, three scruples; and each scruple, twenty grains.—See also Avoirdupois and Weight.
