What a troy ounce is
A troy ounce is 31.1035 grams — about 10% heavier than the ounce on a kitchen scale, which is 28.35 grams. Precious metal has been quoted in troy ounces for centuries and every spot price you see is one.
The unit spot itself is quoted in, and the size of the standard bullion coin: an American Eagle, a Krugerrand and a Maple Leaf each hold one troy ounce of metal.
How this is calculated
Spot per troy ounce ÷ 31.1035 × 31.1035 grams. The conversion is exact: the troy ounce is defined against the troy ounce rather than measured against it.
The headline figure is the published spot price restated in troy ounces and carries its own timestamp. Anything multiplied by a weight you enter waits for a live quote — nothing on this site values your metal from a price we cannot vouch for right now.
Common questions
- How is the gold price per troy ounce worked out?
- Spot gold is quoted per troy ounce, which is 31.1035 grams. The price per troy ounce is that figure divided by 31.1035 and multiplied by 31.1034768 grams, so there are 1 troy ounces in a troy ounce. The conversion is exact — the troy ounce is defined against the troy ounce rather than measured against it.
- Will I be paid the gold price per troy ounce for what I own?
- Only if it is pure gold and you are selling in wholesale quantity, which almost nobody is. Jewelry is an alloy and is worth its fineness share of this figure — and any buyer pays a percentage of that, not the full amount, because they have to refine it and make a living. Coins and bars sell for more than this figure, by the dealer's premium.
- Is a troy ounce the same as a normal ounce?
- No. A troy ounce is 31.1035 grams and the avoirdupois ounce on a kitchen or postal scale is 28.3495 grams, so a troy ounce is about 10% heavier. Every precious metal spot price, coin weight and dealer listing means troy ounces.
