About Kilonewton-meter (kN·m)
A metric unit of torque equal to 1,000 newton-meters. Kilonewton-meters are used for large-scale engineering: industrial turbines, large diesel engines (ship propulsion, locomotives), wind-turbine main shaft torque (a modern 5 MW wind turbine produces ~3,800 kN·m), structural moments on reinforced concrete beams, and crankshaft loads in heavy equipment. Structural design codes (Eurocode, ASCE) use kN·m for bending moments.
About Foot-pound-force (ft·lbf)
An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (about 1.356 N·m). Foot-pounds are the dominant US torque unit — automotive service manuals, wheel-lug torque specs, US-made torque wrenches, and firearms barrel-threading all list ft·lbf. A typical car's lug nut spec is 80–100 ft·lbf. Careful: ft·lbf as torque should not be confused with ft·lb as energy (same name, different dimension).
