When you need this conversion
- Cooking from a foreign recipe, where ingredient weights are given in the author’s local unit.
- Shipping and luggage: carriers publish limits in kilograms in most of the world and in pounds in the United States, and going over costs money.
- Health and fitness tracking, where body weight and equipment loads are quoted in whichever unit the app or gym was set up with.
Getting it right
The ounce (weight, 28.35 g) and the fluid ounce (volume, about 29.6 mL in the US) are different units. A recipe asking for 8 oz of flour and one asking for 8 fl oz of milk are not measuring the same kind of quantity.
Sanity-check the direction of the result before you use it. One pound is 16 ounces, so converting pounds to ounces should make the number larger. If it moved the other way, the conversion was applied backwards — the reverse converter is one click away.
