Troy Pound vs Avoirdupois Pound

The troy pound (373.242 g, 12 troy oz) is lighter than the avoirdupois pound (453.592 g, 16 oz) by 80.35 grams. Despite having fewer ounces, each troy ounce (31.1035 g) is heavier than an avoirdupois ounce (28.3495 g). This counterintuitive relationship confuses many: "a pound of gold weighs less than a pound of feathers" is technically true because gold uses troy weight while feathers use avoirdupois.

Silver bars are typically 1,000 troy oz (83.33 troy lbs = 31.10 kg). Understanding troy pounds helps interpret historical mint records and bullion vault inventories.

The system uses: 24 grains = 1 pennyweight, 20 pennyweight = 1 troy ounce, 12 troy ounces = 1 troy pound. This was adopted by the English mint and remains the legal standard for precious metals in most English-speaking countries.
