Kilogram Force to Newtons Formula

To convert kgf to N, multiply by 9.80665 (exact):

N = kgf × 9.80665

This factor is the exact value of standard gravity (g&sub0;) defined by the 3rd CGPM in 1901.

Worked Example

Convert 10 kgf to N: 10 × 9.80665 = 98.0665 N.

Frequently Asked Questions

How many Newtons is 1 kgf?

Exactly 9.80665 N. This is a defined constant, not an approximation.

Is kgf the same as kg?

No. kgf is a unit of force (the weight of 1 kg under standard gravity). kg is a unit of mass. They are numerically different: 1 kg of mass produces 9.807 kgf... wait, that’s circular. More precisely: 1 kgf = 9.807 N, while 1 kg is just mass.

Why is 9.80665 used instead of 9.81?

9.80665 m/s² is the internationally defined standard gravity (g&sub0;), adopted by the CGPM in 1901. It is an exact constant by definition, not a measured value. The common approximation 9.81 is only accurate to 3 significant figures.

Is kilopond the same as kgf?

Yes. Kilopond (kp) is an older name for kilogram-force, used mainly in German-speaking countries. 1 kp = 1 kgf = 9.80665 N exactly.
