There are 16 ounces of weight in one pound. Multiply pounds by 16, or divide ounces by 16 to go the other way.

1. ½ pound = 8 ounces
2. 1¼ pounds = 20 ounces
3. 2½ pounds = 40 ounces

A kitchen scale measures weight. A measuring jug measures volume. The weight of a fluid ounce depends on what you put in the jug, so you cannot use the pound conversion for a recipe written in fluid ounces. For 1 pound 6 ounces, convert the pound first. Add 16 and 6 to get 22 ounces.
