What is it

Gold is quoted in grams on the Shanghai market but in troy ounces in London and New York — one troy ounce equals 31.1035 grams, not the 28.35 of a kitchen ounce. One wrong unit can misprice a whole bar.

Notes & fun facts

A “1 oz” coin in a foreign catalog is almost always a troy ounce; a kitchen scale reading is not. Interbank gold desks convert constantly — a small unit mistake on a 100 kg vault order is a big number.

Origin & history

The troy ounce system dates to medieval Troyes, France, and became the global standard for precious metals. China’s exchange quotes gold in yuan per gram since 2002, while London quotes US dollars per troy ounce.
