Force units — newtons, kilograms-force, pound-force and more

The newton (N) is the SI unit of force and the basis of all conversions on this page. The kilogram-force (kgf) — called Kilopond (kp) in German — equals the weight of 1 kg under standard gravity gₙ = 9.80665 m/s², giving exactly 9.80665 N. The pound-force (lbf) is the Anglo-American equivalent: 1 lbf = 4.4482216152605 N. The dyne is the CGS unit (1 dyn = 1 × 10⁻⁵ N), and the poundal is another FPS unit (1 pdl = 0.138254954376 N).

All conversion factors are exact defined constants — there is no measurement uncertainty. For more force unit pairs, visit the force conversion hub.

Frequently asked questions

How much is 1 lbf in kgf?

1 lbf equals 0.4536 kgf.

How much is 10 lbf in kgf?

10 lbf equal 4.5359 kgf.

How do I convert lbf to kgf?

Divide the value in lbf by 2.2046 to get kgf.

What is a newton (N)?

The newton (N) is the SI unit of force. 1 N is the force required to accelerate 1 kg by 1 m/s². It is named after Isaac Newton. All other force units relate to the newton through exact defined conversion factors.

What is the difference between kgf and kp (kilopond)?

kgf (kilogram-force) and kp (kilopond) denote the same unit: the weight force of 1 kg under standard gravity gₙ = 9.80665 m/s², giving 1 kgf = 1 kp = 9.80665 N. German technical texts prefer kp; international usage favours kgf. Neither is an SI unit.

Are these force conversions exact?

Yes. All factors used are exact defined constants: 1 kgf = 9.80665 N (standard gravity, exact), 1 lbf = 4.4482216152605 N (exact), 1 dyn = 1 × 10⁻⁵ N (exact), 1 pdl = 0.138254954376 N (exact). There is no measurement uncertainty — only floating-point rounding at the last digit.
