About the units
- Newton
- The SI unit of force: the force that gives a mass of one kilogram an acceleration of one meter per second squared (1 N = 1 kg·m/s²).
- Pound-force
- The weight of one pound (0.45359237 kg) under standard gravity, exactly 4.4482216152605 newtons.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many pounds-force are in one newton?
1 N = 0.224809 lbf exactly.
How do I convert newtons to pounds-force?
Use lbf = N × 0.2248089431. For example, 25 N = 5.62022 lbf.
How many newtons are in one pound-force?
1 lbf = 4.44822 N.
What is the difference between a kilogram and a kilogram-force?
The kilogram is a unit of mass, while the kilogram-force is the weight of that mass under standard gravity, exactly 9.80665 newtons. So a 10 kg object presses down with about 98.07 newtons.
Why are climbing ropes and anchors rated in kilonewtons?
The kilonewton is a standard force unit that suits large loads. As a quick estimate, 1 kN is about 102 kilograms-force.
