Pounds to Ounces (lbs to oz)

How to convert pounds to ounces

Multiply the pounds by 16:

ounces = pounds × 16

2.5 lb × 16 = 40 oz. If the weight is written in pounds and ounces, multiply the pounds and add the ounces: 7 lb 8 oz = 7 × 16 + 8 = 120 oz. Enter the ounces in + ounces and the converter does the addition.

For the other direction, divide ounces by 16 — the ounces to pounds converter shows the result in decimal pounds and in pounds and ounces. The short answer — 16 ounces in a pound — has its own page with the common mix-ups: how many ounces in a pound.

Decimal pounds to ounces

Store scales print weights in tenths and hundredths of a pound. Each tenth is 1.6 ounces, not 1 ounce:

So 1.5 lb of cheese is 24 oz, and 0.75 lb is 12 oz — not 7.5.

Shipping, cooking and baby weights

Ounces are the unit for anything light enough to weigh in fractions of a pound. Postal rates for small parcels step up by the ounce, so a 1.3 lb package is billed as 21 oz rather than “about a pound”. Recipes list meat and cheese in ounces: a 1.25 lb pack of ground beef is 20 oz, enough for five 4 oz patties. Birth weights are given in pounds and ounces, and a newborn of 7.4 lb weighs 7 lb 6.4 oz — the decimal is not the ounces. In each case, multiply the decimal part of the pounds by 16 and add it to the whole pounds times 16.
