Questions
How do I convert one force unit to another?
Enter your value, choose the unit you have under From unit and the unit you want under To unit. The value is turned into newtons first and then into the target unit, so any pair converts in one step.
How do I convert kilogram-force to newtons?
Multiply the kgf value by exactly 9.80665, so 1 kgf is 9.80665 N. A kilogram-force is the weight of a 1 kg mass under standard gravity, and that gravity is a fixed convention rather than a local measurement.
How do I convert newtons to pound-force?
Divide the newton value by 4.4482216, so 1 N is about 0.224809 lbf and 1 lbf is about 4.4482 N. Pound-force is the unit most US engineering uses for weight and applied loads.
What is a newton?
The newton is the SI unit of force — the force needed to accelerate a 1 kg mass at 1 m/s². For a feel of scale, holding a small apple takes about 1 N, and a 1 kg bag of sugar weighs about 9.81 N, which is 1 kgf.
What is a dyne?
The dyne is the unit of force in the older CGS system, equal to exactly 0.00001 newtons. It still turns up in physics and surface-tension work, where 1 N is 100000 dyn.
