Real-world reference

A one-liter bottle of water resting on a scale reads about 1 kgf. Bicycle spoke tension is often specified in kgf. In newtons, that gives you: 1 kgf = 9.80665 N, 10 kgf = 98.0665 N, 100 kgf = 980.665 N.

Frequently asked questions

How many newtons are in 1 kilogram-force?
1 kilogram-force equals 9.80665 newtons.

Multiply the newton value by 0.101972. For example, 1 N = 0.101972 kgf.
Is the kilogram-force bigger than the newton?
Yes. 1 kilogram-force is larger than 1 newton — specifically 9.80665 times larger.
Are these conversion factors exact?
The factor is derived directly from the SI definitions of kilogram-force and newton; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.

About the kilogram-force and the newton

The kilogram-force

The kilogram-force (kgf), also called the kilopond (kp), equals exactly 9.80665 newtons — the force exerted by standard gravity on a one-kilogram mass. It remains common on older European spring scales, some tension gauges, and bicycle spoke-tension specs.

The newton

The newton (N) is the SI derived unit of force, defined as the force required to accelerate a one-kilogram mass at one meter per second squared. It is the standard unit throughout physics and engineering.
