Troy weight 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. One Troy ounce is about 10% heavier than the common Avoirdupois ounce. Avoirdupois is the system of weights using the pound of 16 ounces. Troy weight is the system of weights used for Gold, Silver and Jewels with twelve ounces to the pound.
