How it works
Both units measure weight, so they are always in the same ratio: one ounce equals 0.0625 pounds. The calculator multiplies the number of ounces you type by 0.0625 to give pounds, and when you type into the pounds field it divides by the same factor to give ounces. Because the ratio never changes, doubling the ounces always doubles the pounds. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).
How to convert ounces to pounds
- Write down the value in ounces, for example 16 oz.
- Multiply by the conversion factor 0.0625 (because 1 ounce = 0.0625 lb).
- 16 × 0.0625 = 1 lb.
- To go back from pounds to ounces, divide by 0.0625 – or multiply by 16.
