About force units
Force is what changes the motion of an object. Its SI unit is the newton (N): the force that accelerates a mass of one kilogram by one meter per second squared.
Gravitational units such as the kilogram-force and the pound-force are defined with standard gravity, exactly 9.80665 m/s². That makes every factor on this page exact: 1 lbf is exactly 4.4482216152605 N and 1 kgf is exactly 9.80665 N.
Frequently asked questions
- Is a kilogram the same as a kilogram-force?
- No. The kilogram measures mass and the kilogram-force measures force. A mass of 1 kg weighs 1 kgf only under standard gravity; on the real Earth the weight varies slightly with location.
- Why are pound-force and pound different units?
- The pound (lb) is a unit of mass. The pound-force (lbf) is the force of standard gravity on one pound of mass, exactly 4.4482216152605 N. Engineers write lbf to avoid confusing the two.
- What does "ton-force" mean?
- It depends on the ton. A metric tonne-force is 9806.65 N, a US short ton-force is 2000 lbf and a UK long ton-force is 2240 lbf. This site keeps them as separate units so they are never mixed up.
- How many kilonewtons are in one newton?
- One newton = 0.001 kN (kilonewtons).
- How many dynes are in one newton?
- One newton = 100000 dyn (dynes).
- How many grams-force are in one newton?
- One newton ≈ 101.9716213 gf (grams-force).
