Formula

The newton is the base unit. 1 kgf = 9.80665 N (standard gravity) and 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N.

newtons = lbf × 4.4482216152605
lbf = newtons ÷ 4.4482216152605
1 dyn = 0.00001 N and 1 poundal = 0.138254954376 N

Worked example

From	To	Calculation	Result
100 N	lbf	100 ÷ 4.4482216152605	22.480894
10 lbf	N	10 × 4.4482216152605	44.482216
1 kN	kgf	1000 ÷ 9.80665	101.971621
1 lbf	poundals	4.4482216 ÷ 0.138254954	32.174049

Frequently asked questions

How do I convert newtons to pounds-force?

Divide the newtons by 4.4482216152605. For 100 N that is 100 ÷ 4.4482216 = 22.480894 lbf.

How many newtons is a kilogram-force?

One kilogram-force is exactly 9.80665 newtons, the weight of one kilogram under standard gravity. So 1 kN is about 101.971621 kgf.

What is a poundal?

A poundal is the force that accelerates one pound at one foot per second squared, equal to 0.138254954376 N. One pound-force is about 32.174049 poundals.

Is force the same as weight?

Weight is the force of gravity on a mass. A 10 kg mass weighs about 98.0665 N on Earth, but the same mass has the same mass anywhere.
