Precious metals use troy ounces because this system originated from medieval European bullion trading and became standardized for high-value commodities where precision matters. The troy system's 12-ounce pound differs from avoirdupois's 16-ounce pound, making troy ounces slightly heavier (31.1 grams vs 28.35 grams). International commodity exchanges locked into troy ounce pricing centuries ago, and changing this standard would disrupt trillions of dollars in existing contracts and market infrastructure.
