How to Convert Gram-force to Pound-force
- 1 gf = 0.002204622622 lbf
- 1 lbf = 453.59237 gf
- Example: convert 15 gf to lbf: 15 gf = 15 × 0.002204622622 lbf = 0.03306933933 lbf
Formula
lbf = gf × 0.002204622621849
or lbf = gf ÷ 453.59237
Derivation from SI units:
- 1 gf = 9.80665 × 10⁻³ N (exact)
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 gf = 0.00980665 N ÷ 4.448221615261 N per lbf = 0.002204622621849 lbf
Both units are defined exactly, so the factor is exact. Gram-force definition: gram-force; Pound-force definition: pound-force.
Worked examples
- A reading of 45 gf converts to 0.09920801798 lbf.
45 gf × 0.002204622622 = 0.09920801798 lbf - A value of 100 gf is 0.2204622622 lbf.
100 gf × 0.002204622622 = 0.2204622622 lbf
