MihsabaHow to use
Torque is the moment of a force about an axis, with N·m as the SI unit. This converter normalizes every input to newton-metres and then converts to the chosen target while preserving sign when it represents rotational direction.
- Enter the torque value; a negative sign may be used for direction.
- Choose source and target units.
- Read the selected conversion plus N·m, lbf·ft, lbf·in and kgf·m equivalents.
How it is calculated
Example
Example: 100 N·m ≈ 73.7562 lbf·ft, ≈ 885.0746 lbf·in and ≈ 10.1972 kgf·m. Also, 1 kgf·m = 9.80665 N·m.
Important notes
Although N·m has the same dimensional product as a joule, torque and energy are different physical quantities and should not be interchanged. Factors for kgf·m, lbf·ft, lbf·in, ozf·in and dyn·cm follow standard conversion relationships; kgf uses standard gravity 9.80665 m/s².
Frequently asked questions
How many N·m are in 1 lbf·ft?
Approximately 1.35581795 N·m.
Is N·m the same as a joule?
They share dimensions, but N·m denotes torque and J denotes energy; they are not interchangeable quantities.
Why is 1 kgf·m equal to 9.80665 N·m?
Because kilogram-force is defined using standard gravity, with 1 kgf = 9.80665 N.
