This calculator combines nonnegative avoirdupois pounds and ounces into total ounces. It also reports decimal pounds and equivalent metric mass.

Normalize the mixed-unit entry

Use separate pounds and ounces fields for a mixed weight, then retain the total-unit outputs when checking a label. Do not type a pounds-and-ounces notation as decimal pounds. If recording a parcel, keep the actual scale reading and packaging basis with the result. The normalized quantity is a unit calculation, not a new weighing of the item.

Formula

total oz=(lb×16)+additional oz\text{total oz}=(\text{lb}\times16)+\text{additional oz}

For 3 lb and 8 oz, the total is 56 oz, or 3.5 lb. For the boundary case of 0 lb and 8 oz, the result is 8 oz. The normalized row carries each complete group of 16 ounces into pounds.
