Although the metric system is referred to as the international system of units, Troy weight is still the traditional unit of weight used for precious metals and the jewelry industry. In the bullion market, all references to ounces mean troy ounces. The troy ounce differs from the more common (avoirdupois) ounce used in the United States and in the UK, being somewhat heavier, with 1 troy oz = 1.097 oz.
