How the Unit Converter works

One pound is exactly 453.59237 grams. That is a definition rather than a measurement: the imperial and US customary units were fixed against metric ones by the 1959 international yard and pound agreement, so this factor does not drift and will not be revised.

Worked through: 2 lb x 453.59237 = 907.185 g.

Going the other way, one gram is 0.0022046226 pounds.

To convert without a calculator, multiply by 453.6. Rounding that to 450 is within 0.79% for most purposes.

Recipes, mostly, and the direction that matters for baking. A pound is 453.6 g, so the common recipe quantities convert awkwardly: half a pound is 227 g rather than a round 250, which is why converted recipes often round and change the ratios.

Precision is worth matching to the input. A measurement given as 0.5 lb carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
