Newton-meter (N·m)
The newton-metre (N·m) is the SI unit of torque: a force of one newton acting at one metre from the axis. It is dimensionally equal to a joule but is not written as J.
Symbol: N·m (ASCII: Nm)
Quantity: torque (moment of force)
SI relation: N·m is the coherent SI unit of torque.
Derivation: 1 N·m = 1 N × 1 m = 1 kg·m²·s⁻²
Exact: yes, by definition
Typical uses
- Bolt and wheel-nut tightening torques
- Engine and motor torque
- Torque wrenches and drivers
