Kilogram-Force Meter (kgf·m)
The kilogram-force meter (kgf·m) is the torque from a one kilogram-force applied one meter from the axis — exactly 9.80665 newton-meters at standard gravity.
Kilogram-force meters appear on older Asian and European machinery nameplates and some hydraulic torque charts.
Newton Meter (N·m)
The newton-meter (N·m) is the SI unit of torque — the rotational force applied through a lever arm to turn a shaft, bolt, or rotating body.
Newton-meters specify automotive lug-nut torque, wrench settings, and motor output on machinery nameplates — the force you apply to rotate something.
