Convert Kilograms-force to Kilonewtons
1 kilogram-force is 0.009807 kN. One kilogram-force is exactly 0.00980665 kilonewtons.
One kilogram-force is 0.00980665 kilonewtons. To convert kilograms-force to kilonewtons, multiply by 0.00980665; to go the other way, divide by 0.00980665 or multiply by 101.97162. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert kilograms-force to kilonewtons?
- 1.Take the measurement in kilograms-force.
- 2.Multiply by 0.00980665 — that is how many kilonewtons fit in one kilogram-force.
- 3.To go back the other way, divide by 0.00980665, or multiply by 101.97162.
Worked example: 25 kilograms-force to kilonewtons
- Formula
- kgf × 0.00980665 = kN
- Arithmetic
- 25 × 0.00980665 = 0.245166 kN
- Answer
- 25 kgf = 0.245166 kN
The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilogram-force?
The weight of one kilogram under standard gravity, exactly 9.80665 newtons by the defined value of that gravity. Older European engineering drawings are full of it.
What is a kilonewton?
A thousand newtons. Structural loads, anchor ratings and climbing gear are marked here: a 22 kN carabiner holds about 2.2 tonnes.
How many kilonewtons are in a kilogram-force?
One kilogram-force is 0.00980665 kilonewtons, exactly. Going the other way, one kilonewton is 101.97162 kilograms-force. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
