A troy ounce is a unit of measurement specifically used for weighing precious metals and gemstones, and it is defined as approximately 31.1 grams. This measurement is widely accepted in the industry and is critical for ensuring consistency when buying and selling items such as gold, silver, and other valuable commodities.
