How to convert newton meters to kilogram-force meters
- Take the value in newton meters.
- Use the formula kilogram-force meters = newton meters ÷ 9.80665.
- For example, 1 N·m is 0.102 kgf·m.
About newton meters and kilogram-force meters
Divide newton meters by 9.80665 to get kilogram-force meters, or multiply by 0.10197. For a quick estimate divide by 10, which comes out about 2% low. 100 N·m is 10.2 kgf·m and 350 N·m is 35.69 kgf·m.
Most modern spec sheets and torque wrenches use N·m, but older service manuals, some Asian-market wrenches and many hobby parts still work in kgf·m or kgf·cm. Converting a spec into the unit on your wrench avoids guessing.
Examples
- 1 N·m (one newton meter) is 0.102 kgf·m
- 25 N·m (a 25 N·m bolt torque, an illustrative value) is 2.55 kgf·m
- 110 N·m (a typical car wheel nut torque, an illustrative value) is 11.22 kgf·m
- 400 N·m (a turbo diesel engine’s peak torque, an illustrative value) is 40.79 kgf·m
