What is a Force Converter?

A force converter translates a push or pull measurement between different unit systems. The newton (N) is the SI unit: 1 N = the force needed to accelerate 1 kg at 1 m/s2. The kilonewton (kN) is used in structural engineering. Pound-force (lbf) is used in the US. Kilogram-force (kgf) relates force to familiar mass units. The dyne is used in physics at smaller scales.

Frequently Asked Questions
How many newtons in 1 pound-force?

1 lbf = 4.44822 N.

What is kilogram-force?

1 kgf is the force exerted by gravity on 1 kg at standard gravity (g = 9.80665 m/s2). 1 kgf = 9.80665 N.

What is the difference between mass and force?

Mass (kg) is the amount of matter. Force (N) is mass x acceleration. Weight is the gravitational force on a mass: a 1 kg object has a weight of about 9.8 N on Earth.

What is a dyne?

A dyne is the CGS unit of force. 1 dyne = 10^-5 N = 0.00001 N. Used in physics and chemistry.
