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.
About Ounce-force inches
The ounce-force inch (ozf·in) equals ≈ 7.062 × 10⁻³ N·m, the traditional US unit for small instrument and servo motors. Brushless DC motors for drones, precision positioning stages, and US industrial servo catalogs (Maxon, Pittman) specify stall torque in ozf·in. A typical NEMA 17 stepper motor delivers 80-220 ozf·in. 16 ozf·in = 1 lbf·in. 1 ozf·in ≈ 7.062 × 10⁻³ N·m ≈ 72.0 gf·cm.
