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.
