Gold & Silver – Precious Metals

Troy weight is a system of units of mass that originated in 15th-century England,[1] and is primarily used today in the precious metals industry. Its units are the grainpennyweight (24 grains), troy ounce (20 pennyweights), and troy pound (12 troy ounces). The grain is the same grain used in the more common avoirdupois system. By contrast, the troy ounce is heavier than the avoirdupois ounce, while the troy pound is lighter than the avoirdupois pound.
