www.vocabulary.comI don’t have live updates right now, but I can summarize what “Troy weight” refers to and how it’s generally discussed in current sources.
Core answer
- Troy weight is a historical system of mass units used for precious metals and gemstones, distinct from the avoirdupois system. The standard unit is the troy ounce, which weighs 480 grains, and there are 12 troy ounces in a troy pound. The troy ounce is exactly 31.1034768 grams. This framework remains the conventional reference for weighing gold, silver, and gems in many markets, even as some other applications migrated to different systems.
