What is Kilogram-Force?

Kilogram-force is a traditional, non-SI unit of force equal to the force exerted by gravity on a 1-kilogram mass at standard gravitational acceleration.

Short history of Kilogram-Force

Kilogram-force was widely used in engineering practice before the SI system standardized on the newton; it still appears in legacy documents, torque wrenches and some pressure gauges.

What is Newton?

The newton is the SI derived unit of force, defined as the force required to accelerate a 1-kilogram mass at 1 meter per second squared.

Short history of Newton

Named after Isaac Newton, the unit was formally adopted as the SI unit of force in 1948 by the General Conference on Weights and Measures.
