Definition
An ounce (oz) is an imperial unit used for smaller weights in food packaging, postage, and nutrition labels. A pound (lb) is a larger imperial unit equal to exactly 16 ounces. This converter translates ounces to pounds precisely and supports the reverse.
Origin or History
The ounce comes from the Roman uncia and the pound from the Roman libra. In the modern avoirdupois system, standardized for commerce in medieval England and still used today, there are 16 avoirdupois ounces in 1 pound. The system underpins grocery weights, postal rules, and consumer goods in the U.S. and parts of the U.K.
Current Use
- USPS and courier pricing tiers often use ounces; converting to pounds helps compare services and declare weight correctly.
- Recipes and meal plans list ounces for meat, cheese, and liquids; convert to pounds to scale for families or events.
- Gym and sports gear sometimes lists both; use pounds for totals and ounces for per-item weights like gloves or pucks.
Examples
- 12 oz chicken breast in pounds: 12 ÷ 16 = 0.75 lb.
