convert grams to pounds and ounces calculator

What this calculator does

This tool converts metric weight (grams) into imperial weight using a mixed format: pounds (lb) and ounces (oz). It is useful when a scale gives grams, but your recipe, shipping form, or product label needs pounds and ounces.

How grams convert to pounds and ounces

Conversion constants

• 1 pound (lb) = 453.59237 grams

Calculation method

First, the calculator finds whole pounds. Then it converts the remaining grams into ounces.
