One troy ounce of gold, or more accurately, 1 troy ounce of gold, is 31.1034768 grams of gold with a purity of 999.9%. Its origin comes from the Latin word unica, meaning one-twelfth. The Romans used it. The ounce used today as the British unit of weight is not the same as the troy ounce used for gold. A troy ounce of gold is approximately 4x2 cm in size, less than 1/4 inch of a credit card, and about the same thickness. The price of gold is determined based on this unit, 1 troy ounce. This is because it has been this way for 100 years and is a tradition, set by the Rothschild family bank in London. Choose ounces of gold produced in certified refineries.
