How to Convert Gram-force to Kilonewton
- 1 gf = 0.00000980665 kN
- 1 kN = 101971.6213 gf
- Example: convert 15 gf to kN: 15 gf = 15 × 0.00000980665 kN = 0.00014709975 kN
Formula
kN = gf × 0.00000980665
or kN = gf ÷ 101971.6212978
Derivation from SI units:
- 1 gf = 9.80665 × 10⁻³ N (exact)
- 1 kN = 10³ N
- 1 gf = 0.00980665 N ÷ 1000 N per kN = 0.00000980665 kN
Both units are defined exactly, so the factor is exact. Gram-force definition: gram-force; Kilonewton definition: kilonewton.
Worked examples
- A reading of 45 gf converts to 0.00044129925 kN.
45 gf × 0.00000980665 = 0.00044129925 kN - A value of 100 gf is 0.000980665 kN.
100 gf × 0.00000980665 = 0.000980665 kN

Where it's used
Grams-force are used for keyboard switch actuation force (e.g. 45 gf), while kilonewtons appear in climbing gear strength (carabiners ≈ 22–25 kN). Both measure force, so the conversion is a fixed factor.
