How to convert newton to kilogram-force
Enter your force in newton and get the equivalent in kilogram-force instantly. Key reference points: the weight of an apple is about 1 newton, an average adult weighs about 686 N (154 lbf), and 1 kilogram-force equals exactly 9.80665 newtons.
Newtons (N) are the SI force unit used in physics and engineering, while kilogram-force (kgf) relates force directly to mass under standard gravity (9.80665 m/s²). Kilogram-force is still widely used in material testing, structural engineering and weight specifications in some countries, even though the SI system officially replaced it with newtons. To convert N to kgf, divide by 9.80665 - or for quick estimates, divide by 9.81 or simply by 10.

Frequently asked questions
1 newton equals 0.101972 kilogram-force.
Multiply by 0.101972. For example, 5 N = 0.509858 kgf.
Divide newtons by 9.80665 to get kgf. So 1N = 0.10197 kgf, 100 N = 10.197 kgf and 686.5 N = 70 kgf (the weight of a 70 kg person). Quick mental math: divide newtons by 10 for a close approximation.
1 kilogram-force equals 9.80665 newton.
100 newton equals 10.1972 kilogram-force.
