About Newton and Kilogram-force
Newton (N)
The newton is the SI unit of force — the force needed to accelerate one kilogram by one meter per second squared.
Where it's used: Physics, engineering analysis, and mechanical design.
Kilogram-force (kgf)
A kilogram-force is the force exerted by one kilogram under standard gravity, exactly 9.80665 newtons.
Where it's used: Older engineering specs and fastener torque references in Europe and Asia.
