Pounds to Ounces Converter: Quick and Easy Conversion

The formula

A pound is defined as 16 ounces (avoirdupois), so the conversion is a simple multiplication: ounces = pounds × 16.

Worked example

Enter 2.5 pounds and the tool returns 40 ounces (2.5 × 16 = 40). For a whole number like 3 pounds, you'd get 48 ounces.

Where this comes up

Recipes, shipping labels, and nutrition labels often switch between pounds and ounces depending on the quantity — small amounts (herbs, spices, individual servings) tend to be listed in ounces, while bulk quantities use pounds. This converter doesn't round the result; entering a value like 1.375 lb returns 22 oz exactly (1.375 × 16 = 22).
