Pound (lb t or lb or #) [2]
Pound (lb t or lb or #) [2] :
A second traditional unit of mass or weight. The troy pound, named for the French market town of Troyes, was the unit used in England by apothecaries and jewelers. The troy pound is divided into 12 ounces like the Roman pound. One troy pound is 373.242 grams, or exactly 144/175 = 0.822 858 avoirdupois pounds (13.165 72 avoirdupois ounces). The troy and avoirdupois pounds are connected by the grain: there are 5760 grains in a troy pound and 7000 grains in an avoirdupois pound. See troy weights for additional information. The troy pound should be abbreviated lb. t. to distinguish it from the more common avoirdupois pound
