Convert Kilograms-force to Newtons
1 kilogram-force is 9.80665 N. One kilogram-force is exactly 9.80665 newtons.
One kilogram-force is 9.80665 newtons. To convert kilograms-force to newtons, multiply by 9.80665; to go the other way, divide by 9.80665 or multiply by 0.10197162. 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 newtons?
- 1.Take the measurement in kilograms-force.
- 2.Multiply by 9.80665 — that is how many newtons fit in one kilogram-force.
- 3.To go back the other way, divide by 9.80665, or multiply by 0.10197162.
Worked example: 25 kilograms-force to newtons
- Formula
- kgf × 9.80665 = N
- Arithmetic
- 25 × 9.80665 = 245.16625 N
- Answer
- 25 kgf = 245.16625 N
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 newton?
The SI unit: the force that accelerates one kilogram by one metre per second every second. Holding a small apple against gravity takes about one newton.
How many newtons are in a kilogram-force?
One kilogram-force is 9.80665 newtons, exactly. Going the other way, one newton is 0.10197162 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.
