How we got this
16 ounces (weight) × 28.349523125 g/oz = 453.59237 g
453.59237 g ÷ 453.59237 g/lb = 1 lb
1 oz = 28.349523125 g. 1 lb = 453.59237 g. 1 troy oz = 31.1034768 g (international avoirdupois and troy definitions, NIST).
Density used: water, 1 g/mL. By definition close to 1 g/mL at room temperature. Source: NIST.
Also useful:
There are 16 ounces in a pound, so divide ounces by 16. 8 oz is half a pound, 4 oz is a quarter, and 24 oz is 1.5 lb. This is the ounce on food packaging, kitchen scales and postal scales, and a pound is exactly 453.59237 g. The UK uses the same pound.
Only weight ounces convert to pounds. A fluid ounce measures volume, so 16 fl oz is a pint, not a pound. Water muddies this: 16 US fl oz of water weighs about 1.04 lb, which is where "a pint's a pound" comes from. For any other liquid you need its density first. Troy ounces are a third case: a troy pound has only 12 troy ounces.
