How to Convert Pounds to Ounces
To convert pounds to ounces, multiply the number of pounds by 16, because there are 16 ounces in a pound. The formula is ounces = pounds × 16. The converter above does it instantly. With a factor of 16, round values are easy: 2 pounds is 32 ounces, 5 pounds is 80 ounces.
The Pounds to Ounces Formula
One pound equals exactly 16 ounces (avoirdupois, the system used for food and everyday weight). To convert pounds to ounces, multiply by 16; to convert ounces back to pounds, divide by 16. For a weight given in pounds and ounces, multiply only the pounds by 16 and add the extra ounces.
Worked Examples
1 pound: 1 × 16 = 16 ounces. 2 pounds: 32 ounces. 0.5 pound: 8 ounces. 5 pounds: 80 ounces. A 1.5-pound box is 24 ounces, and a newborn weighing 7 pounds 8 ounces is 120 ounces.
Common Pounds to Ounces Values
Quick reference: 0.5 lb = 8 oz, 1 lb = 16 oz, 2 lb = 32 oz, 3 lb = 48 oz, and 5 lb = 80 oz. Because each pound is exactly 16 ounces, multiplying gives the ounce figure, and the converter handles decimals and pound-and-ounce combinations.
Why Convert Pounds to Ounces?
Pounds and ounces are both standard US weight units, and recipes, shipping, and product labels move between them constantly. Converting pounds to ounces helps when a recipe lists an ingredient in ounces but you bought it by the pound, when postage is priced by the ounce, or when comparing package sizes. It is also common for tracking baby weights and portion sizes, which are often given in pounds and ounces together.
Ounces, Pounds, and Grams
Weight units connect across systems: 16 ounces make a pound, and one pound is about 453.6 grams, so an ounce is about 28.35 grams. This means a 1.5-pound item is 24 ounces or roughly 680 grams. Knowing these links lets you convert into metric when a recipe or scale needs it. The converter supports ounces, pounds, grams, kilograms, and stone, so any weight conversion is one click away.

Pounds-to-ounces conversion is a daily task in several settings.

Baby weights are a classic case: newborns are weighed in pounds and ounces together, like “7 pounds 8 ounces,” which is 120 ounces. Because there are exactly 16 ounces in a pound, these conversions are quick, and the tool handles pound-and-ounce combinations.
Ounces, Pounds, and Grams

That means a 1.5-pound item is 24 ounces or about 680 grams — useful when a recipe or scale uses metric units instead. Being able to move from pounds to ounces, and then to grams when needed, covers almost any weighing task in cooking, shipping, or science. The converter supports ounces, pounds, grams, kilograms, and stone, so you can switch between systems with a single click.
