How pounds to ounces are calculated
A pound is exactly sixteen ounces, so the conversion is one multiplication or its reverse.
ounces = pounds × 16 (1 lb = 453.59237 g)
- One pound is exactly 16 ounces, and one ounce is exactly 28.349523125 grams.
- Multiply your pounds by 16 for ounces, or divide your ounces by 16 to go back.
- A pound is 453.59 grams, so 10 lb is 160 oz, or 4.536 kg.
- These are the avoirdupois weights everyday scales use. Precious metals use a heavier troy ounce of 31.1 g.
Worked example — 3.75 lb × 16 = 60 oz. That is 1,701 grams, or 3 lb 12 oz on a kitchen scale.

Things to consider
- Recipes list ounces and pounds — 32 oz is 2 lb, so half a 24 oz batch is 12 oz, or 0.75 lb.
- Baggage limits are usually in kg or lb: a 23 lb bag is 368 oz, or 10.43 kg.
- A weight ounce is not a fluid ounce — 8 oz of flour by weight is not the same as 8 fl oz of milk.
- Body weight still uses stone: 1 stone is 14 lb, which is 224 oz.
