How to convert pounds to troy ounces
troy ounces = pounds × 14.5833
Example: 5 lb × 14.5833 = 72.92 oz t.
Multiply the pounds by 14.5833. The factor comes from the gram definitions of both units: a pound is exactly 453.59237 grams and a troy ounce is exactly 31.1034768 grams, so one divided by the other gives the multiplier.
For 2 lb, the result is 29.17 oz t. If your scale shows pounds and ounces, turn the ounces into a fraction of a pound first: 2 lb 3 oz is 2.188 lb, which is 31.9 oz t.
To go the other way, use troy ounces to pounds.
Weighing gold or silver on a kitchen scale
A kitchen or postal scale set to pounds reads everyday avoirdupois pounds and ounces. Each of those ounces is 0.9115 oz t, a little less than a troy ounce, so a reading has to be converted before you compare it with a troy weight.
Say a bag of old coins reads 1 lb 5 oz. That is 1.313 lb, or 19.14 oz t in total.
The scale weighs the whole piece, not just the precious metal in it. Coins, bars and jewelry can contain other metals, so the pure gold or silver inside may weigh less than the reading.
For small pieces, switch the scale to grams if it can. Grams come in finer steps than ounces, and pounds to grams shows how the two relate.
Pounds and troy ounces: questions
Why is a pound of gold only 12 troy ounces?
Because that pound is a troy pound, which is 12 troy ounces, or 373.2 g. The everyday avoirdupois pound is heavier at 453.6 g and holds 14.58 oz t. Both pounds are listed in NIST Handbook 44, and this converter uses the avoirdupois one.
How many troy ounces are in one US pound?
There are 14.58 oz t, whether the pound is gold, silver or anything else. The US and the UK share the same avoirdupois pound, so there is no separate US pound to allow for.
Is 1 oz the same as 1 troy oz?
No. A plain oz means the avoirdupois ounce of 28.35 g, while a troy ounce is 31.1 g. NIST asks for the word troy, or a t as in oz t, whenever the troy unit is meant, so an unmarked ounce is the everyday kind.
Is 12 troy ounces the same as 16 regular ounces?
No, and the gap is bigger than it looks. 12 troy ounces weigh 373.2 g, while 16 ounces weigh 453.6 g. Each troy ounce is heavier, but the troy pound has fewer of them, so it ends up lighter.
