Gold Weight Units & Conversions

The units gold is measured in

Gold is bought and sold in different units depending on where you are. The international market quotes in the troy ounce (about 31.1035 grams) — heavier than the everyday ounce used for groceries. Across South Asia and the Gulf, gold is commonly traded by the tola (about 11.6638 grams), while most of the world measures jewellery and small bars in plain grams. Larger investment bars are quoted by the kilogram (1,000 grams).

Because these units describe the same metal, converting between them is just arithmetic — but getting it right matters when you are comparing a per-tola price in Karachi with a per-gram price in London or a per-ounce spot quote in New York.
