Essential Conversion Factors
Pound: International avoirdupois pound (exactly 0.45359237 kg)
lb to g formula
Direct Answer: 1 lb = 453.59237 g, so multiply by 453.59237: g = lb × 453.59237. Going back: lb = g × 0.0022046226.
How to convert pounds to grams
A pound is 0.45359237 kg and a kilogram is 1,000 grams, so one pound is exactly 453.59237 grams. Recipes often round this to 454 g; kitchen scales and food labels in the US and UK use the same figure.
1. lb → g
Multiply the number of pounds by the conversion factor:
Example: 0.75 lb × 453.59237 = 340.2 g.
2. g → lb
To go back, divide by the same factor, or multiply by its reciprocal, 0.0022046226:
Example: 340.2 g ÷ 453.59237 = 0.75 lb.
Mental math: 450 grams per pound
Multiply by 450, then add about 1%. For most cooking the 450 g figure alone is close enough:
2 lb: 2 × 450 = 900 g, plus 9 = 909 g (exact: 907.18 g).
