About Pounds to Ounces
Convert pounds to ounces instantly, with a reference table of common values. The factor is exact: 1 lb = 16.000000071 oz.
A within-imperial conversion needed for US postal rates, food portioning and infant weights, all of which are stated in pounds and ounces.
The pound descends from the Roman libra, which is why its abbreviation is lb. It was defined in 1959 as exactly 0.45359237 kilograms โ an unusually precise figure because it had to reconcile slightly different British and American pounds already in use. It is the standard unit of body weight and food packaging in the United States, and remains in common conversational use in the United Kingdom alongside metric labelling. A standard bag of sugar is 2 lb, and a gallon of water weighs about 8.34 lb.
Worked through with real numbers: 1 lb is 16 oz, 5 lb is 80 oz, 50 lb is 800 oz.
As for the other side of the conversion: A slice of bread weighs about 1 ounce, and a standard tin of soup is around 10.75 oz.
Strictly these are conversions of mass rather than weight โ mass is how much matter something contains, weight is the force gravity exerts on it. The distinction rarely matters on Earth, where the two are proportional, but it is why the same object masses the same on the Moon while weighing about a sixth as much.
