Exactly 5,760 carats equal 1 troy pound. This precise mathematical relationship is the foundation of international gemstone and precious metals trading. To convert any troy pound measurement to carats, multiply by 5,760. For example, 0.5 troy pounds = 2,880 carats, and 2 troy pounds = 11,520 carats. This standardization ensures consistency across gemological certification, insurance valuations, and international jewelry commerce.

The carat became the international standard for gemstone weight because it provides precision for small, valuable objects. One carat equals exactly 200 milligrams, allowing jewelers to measure stones with remarkable accuracy using calibrated scales. Troy pounds are too large for individual gemstones—a single carat represents only 0.000174 troy pounds, making carats far more practical for precise valuation. The Gemological Institute of America (GIA) and all major certification bodies require carat measurements for professional documentation and insurance purposes.
