Conversion Formula
MN·m = ozf·in × 7.061551814e-9
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.
About Meganewton metres
The meganewton metre (MN·m) equals 10⁶ N·m, the unit for the largest rotating machines and extreme structural loads. Offshore wind turbine tower-base bending moments reach 300-800 MN·m in storm conditions; large hydro-generator shaft torques range 100-500 MN·m; ocean-going vessel propulsion crankshaft peak torques 10-100 MN·m. 1 MN·m = 1000 kN·m ≈ 737 562 lbf·ft ≈ 737.6 kip·ft.
