Avoirdupois Weight Conversion Calculator

Convert Avoirdupois Weight

= 16 oz

Multiply by 16
for quick conversions

lb × 16 = oz


To convert lb to oz, use the conversion factor

1 lb = 16 oz

Then divide both sides of the equation by lb, to get the conversion ratio

1 = 16 oz / lb

Using the conversion ratio to complete the unit conversion, basically multiplying the input by 1, the lb units cancel out, and we are left with oz units.

1 lb × 16 oz / lb
= 16 oz
