How to Convert Pounds to Ounces
1 lb = 16 oz exactly. Multiply pounds by 16 to get ounces. So 3 lbs × 16 = 48 oz. This is a clean integer conversion because the avoirdupois pound is defined as exactly 16 ounces. No decimals or rounding involved.
Useful for American recipes calling for ingredients in fractional pounds (e.g. '1.5 lbs ground beef' = 24 oz) or for converting bulk-pack weights to per-portion amounts. A 5 lb bag of flour is 80 oz - useful when meal-planning with per-recipe ounce requirements.

Frequently Asked Questions
Why is a pound 16 ounces?
Tradition from medieval merchant weighing. The avoirdupois system (literally 'goods of weight' from Old French) was standardised by King Edward I in 1303 with 16 oz to a pound. The relationship has been continuous since.
Are recipe ounces always weight ounces?
Usually yes for dry/solid ingredients. Liquids in American recipes use fluid ounces (fl oz) which is a volume measurement. 1 cup = 8 fl oz of any liquid (or 8 oz of water by happenstance because water has density 1 g/ml).
