Different regions developed their own weight systems for gold trading. The troy ounce is the international standard used on exchanges like COMEX and LBMA. Grams are used universally. Tola is the traditional unit in South Asia and parts of the Middle East. Thai gold is measured in baht. US and UK jewelers use pennyweights. Understanding these conversions is essential for comparing gold prices across markets.
