How many oz ina. pound

One avoirdupois pound contains sixteen avoirdupois ounces. This is the ordinary pound-and-ounce relationship used for many food and package weights in the United States. It does not describe fluid ounces.

Meaning and context

To convert pounds to weight ounces, multiply by sixteen. To convert weight ounces to pounds, divide by sixteen. Keeping the quantity type clear prevents a mass conversion from being confused with a volume measurement.

Examples and usage

Two pounds is thirty-two ounces, while eight ounces is half a pound. Twenty ounces is one and one-quarter pounds. A package showing both pounds and ounces can be checked by converting the pounds first and adding the remaining ounces.

What to check

Fluid ounces measure volume and cannot be converted to pounds without information about the substance. Troy ounces and troy pounds belong to a different system as well. Read the product or problem’s units before applying the ordinary sixteen-to-one relationship.
