About the ounces to pounds converter
To convert ounces to pounds, multiply by 0.0625; to convert back, multiply by 16. For example, 16 oz is about 1 lb. Displayed factors and results may be rounded.
An ounce reading from a scale measures mass. It is suitable for an ingredient or parcel measured by weight, but a fluid-ounce mark on a bottle measures volume. You cannot exchange those two quantities without information about the substance's density.
In the avoirdupois system, 1 oz = 1/16 lb = 28.349523125 g. These values are exact.
Both units are defined exactly. Calculations use 50 significant digits and round only for display.
How to convert ounces to pounds
Divide the ounces by 16: lb = oz ÷ 16. So 24 oz = 1.5 lb, 8 oz = 0.5 lb and 48 oz = 3 lb. This works for weight ounces (avoirdupois), the ones on kitchen and postal scales and food packages. Fluid ounces measure volume and need a different conversion.
How to write ounces as pounds and ounces
A decimal answer such as 1.5 lb is not 1 lb 5 oz. To write a weight as pounds and ounces, divide by 16: the whole number is the pounds and the remainder is the ounces.
- 54 oz: 3 × 16 = 48, remainder 6, so 3 lb 6 oz (3.375 lb)
- 20 oz: 1 × 16 = 16, remainder 4, so 1 lb 4 oz (1.25 lb)
- 100 oz: 6 × 16 = 96, remainder 4, so 6 lb 4 oz (6.25 lb)

Comparing a package with a price per pound
When one product is labeled in ounces and another is priced per pound, convert the ounces first. A 24 oz package is 1.5 lb, so its price per pound is the package price divided by 1.5.
The unit price comparison calculator compares packs in ounces, pounds or grams side by side.
Fluid ounces and troy ounces
- Fluid ounces (fl oz) measure volume, so a 16 fl oz bottle has no fixed weight in pounds; it depends on the contents. For volume, use US fluid ounces to milliliters.
- Troy ounces (oz t) weigh precious metals and are heavier: 31.1034768 g against 28.349523125 g. A 100 oz t silver bar weighs 6.86 lb, not 6.25 lb. The weight converter includes troy ounces.
Both ounces have exact legal definitions. Gibraltar's Weight and Measures Act, Schedule 1, Part V defines the ounce as 1/16 pound, the pound as exactly 0.45359237 kg and the troy ounce as 480 grains.
Common mistakes
- Dividing by 10. 24 oz is 1.5 lb, not 2.4 lb, because a pound has 16 ounces.
- Multiplying instead of dividing. 16 oz would become 256 lb. The pound figure must be the smaller number.
- Writing pounds and ounces as a decimal. 3 lb 6 oz is 3.375 lb, not 3.6 lb. Convert the whole weight to ounces first (3 × 16 + 6 = 54 oz), or type it as
3*16+6.
