It is internationally recognized and standardized by the International Bureau of Weights and Measures (BIPM) for trade and gemology. One carat equals exactly 0.2 grams according to ISO standards [bipm-si-brochure]. The carat originated from the carob seed, historically used as a reference mass. It was standardized in 1907 by the International Committee of Weights and Measures at 200 mg to ensure uniformity in gemstone trade and valuation [bipm-si-brochure]. Carats are globally used in the jewelry industry to weigh diamonds, sapphires, and other gemstones. Countries including the US, UK, Canada, and most of Europe rely on the carat for gemstone mass measurement, aligned with ISO and BIPM standards [bipm-si-brochure].
