Gram to Pound (g to lb)
Result
0.002204622622 Pound
Formula
lb = g × 0.002204622622
1 g = 0.002204622622 lb, and 1 lb = 453.59237 g.
The kilogram is the SI base unit of mass, defined through the Planck constant since 2019. The international avoirdupois pound is exactly 0.45359237 kg; the ounce is 1/16 lb and the stone 14 lb.
Worked examples
- 1 g × 0.002204622622 = 0.0022046226 lb
- 10 g × 0.002204622622 = 0.022046226 lb
- 100 g × 0.002204622622 = 0.22046226 lb
Common mistakes
- Precious metals use the troy ounce (31.1034768 g), about 10% heavier than the avoirdupois ounce (28.349523125 g) used for food and parcels.
- "Ton" is ambiguous: the metric tonne used here is 1,000 kg, the US short ton 907.18474 kg and the UK long ton 1,016.0469088 kg.
- Kilograms and pounds measure mass. Pound-force (lbf) and newtons measure force — they are not interchangeable with kg.
