About Kilonewton and Kilogram-force

Kilonewton (kN)

A kilonewton is 1,000 newtons, roughly the weight of a 102 kg mass.

Where it's used: Structural loads, crane capacities, and material strength specs.

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.
