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 Kilonewton metres
The kilonewton metre (kN·m) equals 1000 N·m, the standard unit for structural and civil engineering bending moments and large-machine torques. Steel beam connection bolts, industrial gearbox output shafts, ship propeller shaft flanges, and large AC induction motor ratings are specified in kN·m. Wind turbine mainshaft torques reach 1-10 MN·m. 1 kN·m = 1000 N·m ≈ 737.6 lbf·ft ≈ 0.7376 kip·ft ≈ 102.0 kgf·m.
