How to convert ounces to pounds
One ounce equals 0.0625 pounds, so multiply the number of ounces by 0.0625:
lb = oz × 0.0625
oz = lb ÷ 0.0625 (1 lb = 16 oz)
Example: 4 oz → 4 × 0.0625 = 0.25 lb.
Going the other way, divide by 0.0625, or multiply by 16; the pounds to ounces converter does it for you.
