There are exactly 5,760 grains in one troy pound. This precise relationship comes from the troy weight system's structure: 1 troy pound = 12 troy ounces, 1 troy ounce = 20 pennyweights, and 1 pennyweight = 24 grains. Multiplying these together (12 × 20 × 24) gives 5,760 grains. This exact ratio has been standardized for centuries in precious metals trading and remains the official conversion used worldwide.

Troy weight emerged from medieval precious metals trading in Troyes, France, and became standardized because it divides more conveniently for small quantities of valuable materials. The troy system's structure (12 ounces per pound, 20 pennyweights per ounce, 24 grains per pennyweight) allows precise measurement of small amounts without decimals. International precious metals markets have used troy weight for centuries, making it the universal standard. Switching would disrupt global commodity trading, so troy weight remains official despite the metric system's dominance elsewhere.
