The kilonewton
The kilonewton (kN) equals exactly 1,000 newtons. It is the practical unit for structural engineering loads, vehicle towing and braking forces, and climbing-gear strength ratings, where whole newtons would produce unwieldy figures.
Kilonewtons to Kilogram-force Converter
1 kN = 101.972 kgf (kilonewton → kilogram-force)
1 kN = 101.972 kgf
1 kilonewton equals 101.972 kilogram-force. To convert kilonewtons to kilogram-force, multiply the kilonewton value by 101.972. For quick reference: 1 kN = 101.972 kgf, 5 kN = 509.858 kgf, 10 kN = 1019.72 kgf, 100 kN = 10197.2 kgf.
Formula
Kilogram-force = Kilonewtons × 101.972Quick

Real-world reference
A climbing carabiner is typically rated to 20–24 kN. A mid-size car's braking force can exceed 5 kN. In kilogram-force, that gives you: 1 kN = 101.972 kgf, 10 kN = 1019.72 kgf, 100 kN = 10197.2 kgf.
Frequently asked questions
- How many kilogram-force are in 1 kilonewton?
- 1 kilonewton equals 101.972 kilogram-force.

About the kilonewton 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.
