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.
Newtons to Kilogram-force Converter
1 N = 0.101972 kgf (newton → kilogram-force)

Real-world reference
An average apple weighs about 1 N under Earth gravity. A firm handshake grip exerts roughly 50 N of force. In kilogram-force, that gives you: 1 N = 0.101972 kgf, 10 N = 1.01972 kgf, 100 N = 10.1972 kgf.
Frequently asked questions
- How many kilogram-force are in 1 newton?
- 1 newton equals 0.101972 kilogram-force.

About the newton and the kilogram-force
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.
