Pounds to Grams Converter (lb to g)

Butcher counters, produce scales and older American cookbooks quote pounds, while bakers who weigh ingredients, nutrition apps and most recipes from elsewhere use grams. A pound is exactly 453.59237 g, so a 1.5 lb roast is about 680 g and a 5 lb bag of flour about 2,268 g.

The chart covers fractions of a pound in the steps a scale or recipe uses, such as an eighth (0.125 lb) and five eighths (0.625 lb), up to 10 lb. For larger amounts in kilograms, the kilograms to pounds converter has charts in both directions.

Example

Two conversions worked with the same factors the converter uses:

1.5 lb × 453.59237 ≈ 680.389 g

Quick mental estimate

Count about 450 g to the pound and add 1% at the end: 2 lb → 900 + 9 = 909 g. That works out to 454.5 g per pound, about 0.2% above the exact 453.59 g.

Use the converter or the charts when the exact figure matters.
