About Pound-force feet
The pound-force foot (lbf·ft) equals ≈ 1.35582 N·m, the dominant torque unit in North American automotive and mechanical engineering. SAE engine performance tests, US vehicle lug-nut torque specs (80-100 lbf·ft), and American industrial gearbox catalogs all use lbf·ft. V8 truck engines produce 400-600 lbf·ft; diesel pickups exceed 900 lbf·ft. 1 lbf·ft ≈ 1.35582 N·m = 12 lbf·in ≈ 192 ozf·in.
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.
