Kilopond- meter or meter- kilopond is an outdated (non- SI- compliant) unit of the technical system of units . It was used for the two quantities energy and torque .

energy

The energy that is applied for a movement is the product of the path and the force that acts in the direction of the path.

• 1  kp m = 1,000 p m,
• 1 kp · m = 9.80665 kg · m² / s² = 9.80665 N · m = 9.80665 J, corresponding to 1 J = 0.102 kp · m,
• 1 kp m ≈ 2.342 cal.

This unit has been obsolete since the introduction of the SI system (in the middle of the 20th century) and was replaced by the joule . The conversion factor 9.80665 comes from setting the standard gravity and is accurate. Its precision is usually limited to the numerical value 9.81 in use.

Torque

The torque is the product of the length of a lever arm and the force acting perpendicularly on the lever.

• 1 kp · m = 9.80665 kg · m² / s² = 9.80665 N · m.

This unit has been obsolete since the introduction of the SI system (in the middle of the 20th century) and has been replaced by the newton meter . The conversion factor 9.80665 comes from the determination of the standard gravity and is exact. Its precision is usually limited to the numerical value 9.81 in use.
