How does this tool work?
This converter turns pounds (lb) into grams and grams into pounds: type a value in either field and the other updates instantly. It is mostly a kitchen tool, for following a European or metric recipe with a scale set to grams, but it also helps with nutrition labels, the net weight of imported food, parcel weights and lab or hobby work that uses metric units.
The pound (symbol lb) is the international avoirdupois pound, defined by the 1959 international yard and pound agreement: 1 lb = 0.45359237 kg, which is exactly 453.59237 g. It is divided into 16 ounces (oz) of 28.349523125 g each.
To convert pounds to grams, multiply by 453.59237; to convert grams to pounds, divide by 453.59237 (or multiply by 0.00220462). For an amount written in pounds and ounces such as "1 lb 4 oz", convert to ounces first (1 × 16 + 4 = 20 oz), then multiply by 28.349523125: about 567 g.
In your head, count 450 g per pound and add 1%: 2 lb → 900 + 9 = 909 g (exact value 907.18). The other way, 500 g is a little over a pound (1.10 lb) and 250 g a little over half a pound (0.55 lb).
Classic pitfall: a "pound" in a French or German shop usually means 500 g, a legacy of the 19th-century metric pound. A European recipe calling for "une livre" or "ein Pfund" therefore expects 500 g, about 46 g more than 1 lb.
How to use this tool
Enter an amount
Use decimal pounds (1.25 lb) or grams; for pounds and ounces, turn the ounces into a fraction of a pound first (4 oz = 0.25 lb).
Read the conversion
The result uses the exact factor; round to the nearest gram for a recipe, to a tenth for postage.
Use the table
The table lists common kitchen amounts (¼ lb, ½ lb, 1 lb…) and, the other way, typical metric pack sizes (125 g, 250 g, 500 g…).

- Benchmarks: ½ lb ≈ 227 g, 1 lb ≈ 454 g, 2 lb ≈ 907 g; 100 g ≈ 0.22 lb.
- A pound has 16 ounces: 8 oz = ½ lb ≈ 227 g and 4 oz (one US stick of butter) = ¼ lb ≈ 113 g.
- To turn a price per pound into a price per kilogram, divide it by 0.45359237.
- Cups measure volume, not weight: a pound of flour cannot be converted to cups without knowing how densely it is packed.
- For body weight or heavy loads, the kg ↔ lbs converter is a better fit.
