Kilogram-force (kgf or kgf) is a unit of force that is defined as the force exerted by one kilogram of mass in a standard gravitational field, which is typically taken to be 9.80665 meters per second squared (m/s²) at sea level on Earth. Thus, one kilogram-force is equal to the gravitational force on a mass of one kilogram. Mathematically, it can be expressed as: 1 kgf = 1 kg × 9.
