Convert between newtons, pound-force, kilogram-force, and more.
Popular force conversions
Newtons to Pound-force1 N = 0.224809 lbf. Gravity on Earth exerts 9.80665 N per kg, so a 1 kg mass weighs 2.205 lbf.Pound-force to Newtons1 lbf = 4.44822 N. A 100 lbf load equals 444.8 N. Gravity on Earth: 1 lb mass weighs 1 lbf = 4.448 N.Kilogram-force to Newtons1 kgf = 9.80665 N. This is Earth's standard gravity. A 10 kgf load = 98.0665 N in structural engineering.Newtons to Kilogram-force1 N = 0.101972 kgf. A 1 kg object on Earth weighs 9.80665 N = 1 kgf. Divide newtons by 9.80665 to convert.

What is force?
Force is any interaction that causes an object to change its motion (F = ma).
Common use cases
- Structural and mechanical engineering
- Physics calculations
- Load and tension analysis
- Spring and cable force ratings
- Bolt and fastener load specs
Ambiguity notes
Do not confuse lbf (pound-force) with lb (pound-mass). They are numerically equal at standard gravity but are fundamentally different quantities.
kgf (kilogram-force) is not an SI unit but is still widely used in engineering contexts, especially in European and Asian industry.
