Force Unit Definitions

Newton (N)
The SI unit of force = 1 kg·m/s². Named after Isaac Newton.
Pound-force (lbf)
The gravitational force on a 1-pound mass = 4.44822 N.
Kilogram-force (kgf)
The gravitational force on a 1-kg mass = 9.80665 N.
Kilonewton (kN)
1,000 N. Used in civil and structural engineering.

Frequently Asked Questions

What is the difference between mass and force?

Mass (kg) is a property of matter; force (N) depends on mass and acceleration (F = ma). Weight is a force — the gravitational pull on a mass.

How many newtons is 1 kg?

A 1 kg mass weighs 9.80665 N (about 9.8 N) under standard gravity.
