What is the kilogram-force unit?

Kilogram-force (kgf) is a gravitational force unit defined as the force exerted by standard gravity on a one-kilogram mass, equal to 9.80665 newtons.

Why convert kilogram-force to kilonewton?

Converting kgf to kN translates legacy gravity-based force measurements into SI units preferred for accuracy and international engineering standards.

Are there any precision concerns when using this conversion?

Yes, since kilogram-force depends on standard gravity and is non-SI, local gravity variations and rounding can affect conversion precision.
