How to Convert Kilogram-force to Pound-force
- 1 kgf = 2.204622622 lbf
- 1 lbf = 0.45359237 kgf
- Example: convert 15 kgf to lbf: 15 kgf = 15 × 2.204622622 lbf = 33.06933933 lbf
Formula
lbf = kgf × 2.204622621849
Derivation from SI units:
- 1 kgf = 1 kg × 9.80665 m/s² = 9.80665 N (exact)
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 kgf = 9.80665 N ÷ 4.448221615261 N per lbf = 2.204622621849 lbf
Both units are defined exactly, so the factor is exact. Kilogram-force definition: kilogram-force; Pound-force definition: pound-force.
Worked examples
- 50 kgf is 110.2311311 lbf.
50 kgf × 2.204622622 = 110.2311311 lbf - A 200 kgf load is 440.9245244 lbf.
200 kgf × 2.204622622 = 440.9245244 lbf
