Kilopond)

The deprecated unit **kilogram-force** (**kgf**) or **kilopond** (**kp**) is the force exerted by one kilogram of mass in standard Earth gravity (defined as exactly 9.806 65 m/sē). One kilogram-force is equal to exactly 9.806 65 newtons.

The kilogram-force has never been a part of the International System of Units (SI), which was introduced in 1960. The SI unit of force is the newton.

Grams-force and kilograms force were never well-defined units until the CGPM adopted a *standard acceleration of gravity* of 980.665 cm/s² for this purpose in 1901, though they had been used in low-precision measurements of force before that time.
