One exact number: sixteen
Some conversions need a choice, like US or UK, but oz to lbs has just one fixed ratio. Sixteen ounces make a pound, always. This page multiplies or divides by that number and hands back the mixed lb and oz format you actually read on a label, so you spend zero time doing the subtraction by hand.
Why use this oz to lbs converter?
No rounding, no guessing
Sixteen ounces to the pound is exact by definition, not an approximation. Every result you see is the precise answer, not a rounded shortcut.
Reads like a shipping label
Results show both the decimal pound and the lb + oz breakdown side by side, the same format used on parcels, growth charts, and butcher paper.

Convert ounces up to pounds or pounds down to ounces. Swap without retyping the number you already entered.

How this Oz to Lbs Converter works
Type a number and this converter divides or multiplies it by 16, the exact number of ounces in one avoirdupois pound. Nothing here is rounded or estimated — 16 oz has equaled 1 lb by definition since the pound was standardized, so the answer you see is exact down to as many decimal places as you choose.
Switch direction and the tool flips the operation: pounds to ounces multiplies by 16 instead of dividing. Either way, every result also shows the mixed lb and oz format printed on shipping labels and growth charts, so 45 oz becomes both 2.8125 lb and the more familiar 2 lb 13 oz without you doing the subtraction yourself.
This is the avoirdupois ounce, the one used for food, body weight, and parcels. It is not the troy ounce used to price gold and silver, which splits into a 12-ounce pound instead of 16. If a number you are converting relates to precious metals, this page is not the one you want.
A decimal control sets how many places to show, useful when a spec sheet or a customs form asks for a specific precision. The common presets cover typical package and body weight checkpoints, including the 16 oz mark where USPS First-Class Package rates change to Priority Mail.
