How to Convert Kilogram-force to Newton
- 1 kgf = 9.80665 N
- 1 N = 0.1019716213 kgf
- Example: convert 15 kgf to N: 15 kgf = 15 × 9.80665 N = 147.09975 N
Formula
N = kgf × 9.80665
Derivation from SI units:
- 1 kgf = 1 kg × 9.80665 m/s² = 9.80665 N (exact)
- 1 N = 1 kg·m/s²
Both units are defined exactly, so the factor is exact. Kilogram-force definition: kilogram-force; Newton definition: newton.
Worked examples
- 1 kgf is exactly 9.80665 N.
1 kgf × 9.80665 = 9.80665 N - A grip strength of 50 kgf is 490.3325 N.
50 kgf × 9.80665 = 490.3325 N
