Convert Pounds-force to Kilonewtons
1 pound-force is 0.004448 kN. One pound-force is exactly 0.00444822161526 kilonewtons.
One pound-force is 0.0044482216 kilonewtons. To convert pounds-force to kilonewtons, multiply by 0.0044482216; to go the other way, divide by 0.0044482216 or multiply by 224.80894. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The weight of one pound under standard gravity, exactly 4.4482216152605 newtons.

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 pounds-force to kilonewtons?
- 1.Take the measurement in pounds-force.
- 2.Multiply by 0.0044482216 — that is how many kilonewtons fit in one pound-force.
- 3.To go back the other way, divide by 0.0044482216, or multiply by 224.80894.
Worked example: 25 pounds-force to kilonewtons
- Formula
- lbf × 0.0044482216 = kN
- Arithmetic
- 25 × 0.0044482216 = 0.111206 kN
- Answer
- 25 lbf = 0.111206 kN
The factor is rounded for display; the figure above is computed from the full value.

What is a pound-force?
The weight of one pound under standard gravity, exactly 4.4482216152605 newtons. A pound of mass and a pound-force are different quantities that share a name, which is why this unit exists at all.
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 pound-force?
One pound-force is 0.0044482216 kilonewtons. Going the other way, one kilonewton is 224.80894 pounds-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.
