Pounds to ounces
Enter a weight in pounds to get it in ounces. Useful when a service prices by the ounce and you have the weight in pounds, or when a label needs pounds and ounces separately.
Type a weight in pounds and the conversion appears here.
Why this conversion matters for shipping
Lighter parcel services often price in ounces, while scales and product listings usually give pounds. A package quoted at 1.3 lb is 20.8 oz, which matters when the price steps at every ounce. Getting it wrong in the wrong direction means either overpaying or having postage rejected.
The conversion
One pound is exactly 16 ounces, so multiply pounds by 16. This is a definition, not an approximation, so there is no rounding error to worry about.
- 1 lb = 16 oz
- 1.5 lb = 24 oz
- 0.25 lb = 4 oz

Common questions
- How many ounces are in a pound?
- Exactly 16.
- My label wants pounds and ounces separately. What do I enter?
- The whole pounds, then the remainder in ounces. 1.3 lb is 1 lb 4.8 oz. The summary above shows that reading for whatever you type.
- Should I round up when buying postage?
- Carriers generally round the weight up to the next priced increment, so a package just over an ounce boundary is priced at the higher step. Weigh with the packaging on, and do not round down.
- Does the packaging count?
- Yes. Carriers weigh the whole package, so weigh it sealed and labelled.
