Conversion Formula
N·m = N·mm × 0.001
About Newton millimetres
The newton millimetre (N·mm) equals 10⁻³ N·m, widely used in mechanical engineering and FEA software. ANSYS, Abaqus, and Siemens NX models built in millimetres report torques in N·mm for dimensional consistency. Fastener torque for M3-M6 screws (typically 0.3-5 N·m range), micro-pump impeller loads, and precision gearbox calibration values are expressed in N·mm. 1 N·mm = 10⁻³ N·m = 0.1 N·cm ≈ 8.851 × 10⁻³ lbf·in.
About Newton metres
The newton metre (N·m) is the SI coherent derived unit of torque and bending moment. Car engine torque is commonly quoted in N·m - a family hatchback delivers 150-250 N·m; a performance saloon 400-600 N·m. Fastener pre-load torques, EV traction-motor ratings, and structural connection bolt specifications are all given in N·m. 1 N·m = 100 N·cm = 1000 N·mm ≈ 0.7376 lbf·ft ≈ 8.851 lbf·in.
