Convert Newtons to Kilograms-force

1 newton is 0.101972 kgf. One newton is exactly 0.101971621298 kilograms-force.

One newton is 0.10197162 kilograms-force. To convert newtons to kilograms-force, multiply by 0.10197162; to go the other way, divide by 0.10197162 or multiply by 9.80665. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The SI unit: the force that accelerates one kilogram by one metre per second every second.

How do you convert newtons to kilograms-force?

  1. 1.Take the measurement in newtons.
  2. 2.Multiply by 0.10197162 — that is how many kilograms-force fit in one newton.
  3. 3.To go back the other way, divide by 0.10197162, or multiply by 9.80665.

Worked example: 25 newtons to kilograms-force

Formula
N × 0.10197162 = kgf
Arithmetic
25 × 0.10197162 = 2.549291 kgf
Answer
25 N = 2.549291 kgf

The factor is rounded for display; the figure above is computed from the full value.

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.

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.

How many kilograms-force are in a newton?

One newton is 0.10197162 kilograms-force. Going the other way, one kilogram-force is 9.80665 newtons. 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.
