Ounces to Pounds (oz to lb) Converter and Formula
1 ounce equals 0.0625 pounds — multiply the number of ounces by 0.0625, or simply divide by 16, to convert. There are exactly 16 ounces in an avoirdupois pound, which makes this one of the cleanest weight conversions: 1 oz = 1/16 lb = 0.0625 lb.
The formula
To convert ounces to pounds, multiply by 0.0625:
lb = oz × 0.0625
For example, 8 oz is 8 × 0.0625 = 0.5 lb (half a pound). To reverse it, divide by 0.0625 (or multiply by 16).

Where this conversion is used
Ounce-to-pound conversion is everyday work in cooking and baking, grocery pricing, postal and courier weight brackets, and mailing packages in the US. Because both units are avoirdupois, it also appears in recipes that mix pound-and-ounce quantities, such as "1 lb 8 oz". Because there are exactly 16 ounces to a pound, the common fractions are worth memorising: 4 oz = 0.25 lb (a quarter pound), 8 oz = 0.5 lb (half a pound) and 12 oz = 0.75 lb (three-quarters of a pound). To turn a decimal-pound answer back into pounds and ounces, take the whole number as pounds and multiply the remaining fraction by 16 — for example 2.375 lb is 2 lb 6 oz. The converter below handles either direction instantly.
