Kilograms-Force to Newtons Converter

Convert kilograms-force to newtons (N) and back. A kilogram-force is the pull that standard gravity puts on one kilogram of mass, which is why it maps to a fixed number of newtons.

Quick answer
One kilogram-force is 9.80665 N, the exact standard-gravity value, so multiply kilograms-force by 9.80665 to get newtons. A 10 kgf load is about 98.07 N. This is a force, not a mass: the kilogram-force is what gravity does to a kilogram, whereas the plain kilogram is the mass itself. To reverse, multiply newtons by 0.10197.

How to convert kgf to N

N = kgf × 9.80665reverse: kgf = N × 0.10197 · g = 9.80665 m/s squared

newtons in one kilogram-force (standard gravity)

A kilogram-force uses standard gravity, 9.80665 m/s squared. Where gravity differs the real force shifts slightly, but the converter uses the standard figure the unit is defined by.

Do not mix this up with mass. A scale reading in kilograms is telling you mass; the force it takes to hold that mass up is the kilogram-force.

Frequently asked questions

How many newtons is 1 kgf?

One kilogram-force is 9.80665 newtons under standard gravity.

How many kgf is 100 N?

100 newtons is about 10.2 kilograms-force.

Is kilogram-force the same as a kilogram?

No. A kilogram is mass; a kilogram-force is the force gravity applies to that mass, and it equals 9.80665 N.

What is 50 kgf in newtons?

50 kilograms-force is about 490.3 newtons.

Why is the factor 9.80665?

That is the defined value of standard gravity in metres per second squared, and force equals mass times acceleration.
