| Pound (lb) | Ounce (oz) |
|---|---|
| 1 | 16 |

| 10 | 160 |
| 25 | 400 |
| 50 | 800 |
| 100 | 1600 |
A pound is exactly 16 ounces, so the arithmetic is simple; the trouble comes from decimal pounds. Digital scales at the deli counter, in the produce aisle and at the doctor's office show readings such as 2.75 lb, while recipes, baby books and fishing logs speak in pounds and ounces. Multiplying the decimal part by 16 turns one form into the other.
The first chart gives each pound value both as plain ounces and as pounds plus ounces. Fractions ordered at a meat counter, such as a third or two thirds of a pound, appear as 0.33 and 0.66, the way a scale prints them.

Quick mental estimate
Multiply only the decimal part by 16: 2.75 lb → 0.75 × 16 = 12, giving 2 lb 12 oz. Each tenth of a pound adds 1.6 oz, which helps with readings like 1.3 lb (1 lb 4.8 oz). Nothing is rounded, so the result is exact.
Use the converter or the charts when the exact figure matters.
