About the pound and the ounce
The avoirdupois pound divides into 16 ounces. It is the everyday unit for body weight and groceries in the United States and is still common in the United Kingdom.
The avoirdupois ounce is one sixteenth of a pound. It appears on US food packaging, postal rates and kitchen scales. Fluid ounces measure volume and are a different unit, and precious metals use the heavier troy ounce of 31.1035 grams.
One pound equals 16 ounces, which makes the pound the heavier unit of the two.
