The kilogram-force (kgf or kgF), or kilopond (kp, from Latin pondus meaning weight), is a gravitational metric unit of force. It is equal to the magnitude of the force exerted by one kilogram of mass in a 8.0665100000000050.66510000000005226.6510000000004086.5100000000047665.1000000000494765 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). Therefore one kilogram-force is by definition equal to 8.0665100000000050.66510000000005226.6510000000004086.5100000000047665.1000000000494765 . Similarly, a gram-force is 8.0665100000000050.66510000000005226.6510000000004086.5100000000047665.1000000000494765 mN, and a milligram-force is 8.0665100000000050.66510000000005226.6510000000004086.5100000000047665.1000000000494765 uN.
