How it works

lb = oz ÷ 16

One pound is exactly 16 ounces, so dividing by 16 gives you pounds as a decimal. The whole number is your pounds. Multiply what's left over by 16 to turn it back into ounces.

  1. Divide by 16 to get pounds 21 ÷ 16 = 1.313 lb
  2. Keep the whole pounds round down 1.313 → 1 lb
  3. Turn the leftover into ounces (1.313 − 1) × 16 = 5 oz
