applied to a measure of weight, of which the pound avoirdupois, weighing 7000 grains troy, and the pound troy, weighing 5760 grams, are used in England. The former is divided into 16 ounces and the latter into 12 ounces. (See Weights and Measures.)
Pound is also a denomination of money, being equal in value to 20 shillings or 240 pence. Anciently 240 pence were equivalent to a pound weight of silver. Hence the origin of the term.
