Ounces to Pounds

American food labels state net weight in ounces, and once a package reaches a pound they usually add the pound figure in parentheses, along with grams. A bag marked NET WT 24 OZ (1 LB 8 OZ) 680 g is one and a half pounds. Cans, cereal boxes and coffee bags trade on this: a 12 oz bag of coffee is three quarters of a pound, a size that replaced the traditional one-pound can in many stores.

Comparing unit prices is the practical reason to convert. A 28 oz jar at $4.20 costs $2.40 per pound, while a 16 oz jar at $2.60 costs $2.60 per pound, so the bigger jar is cheaper per unit even though the shelf tag may show price per ounce instead.

Divide by 16 and keep the whole number as pounds; the remainder is the ounces left over. 54 oz ÷ 16 is 3 with 6 left, so 54 oz is 3 lb 6 oz, or 3.375 lb as a decimal. Shipping software usually wants the decimal, while a recipe or a baby book wants pounds and ounces.

Carriers in the US round up to the next whole ounce or pound depending on the service, so a 15.2 oz parcel may be billed as 16 oz, which is exactly 1 lb.

An ounce on a label can mean weight (oz, NET WT) or volume (fl oz). Only weight ounces convert to pounds by dividing by 16. A 64 fl oz carton of juice is half a US gallon of liquid, and it weighs a little over 4 lb, but that is a property of the juice, not a unit conversion. For volume, use milliliters to fluid ounces instead.

The reverse direction is on pounds to ounces, and the unit converter covers grams, kilograms and stone too.
