Kilopondmetre
The Kilopondmetre is an obsolete unit of torque and energy in the gravitational metric system. It is abbreviated kp·m or m·kp, older publications often use mkg and kgm as well.
Torque is a product of the length of a lever and the force applied to the lever. One kilopond is the force applied to one kilogram due to gravitational acceleration; this force is exactly 9.80665 N.
This means 1 kp·m = 9.80665 kg·m2/s2 = 9.80665 N·m.
