The kilogram-force (kgf or kgF), or kilopond (kp, from Latin: pondus, lit. 'weight'), is a non-standard gravitational metric unit of force. It is not accepted for use with the International System of Units (SI)[1] and is deprecated for most uses.[citation needed] The kilogram-force is equal to the magnitude of the force exerted on one kilogram of mass in a 9.80665 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth).[2] That is, it is the weight of a kilogram under standard gravity. One kilogram-force is defined as 9.80665 N.[3][4] Similarly, a gram-force is 9.80665 mN, and a milligram-force is 9.80665 μN.
