Sixteen ounces to the pound, unless it is gold
The avoirdupois pound is 16 ounces of 28.349523125 g. The troy pound, used for precious metals, is 12 troy ounces of 31.1034768 g — a heavier ounce in a lighter pound. So a troy ounce of gold is about 10% more metal than the ounce on a kitchen scale, and a "pound of gold" is 373.24 g against 453.59 g of anything else. Bullion is quoted per troy ounce and nothing else is.
