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 Inch-pound-force (in·lbf)

An imperial unit of torque equal to one pound-force applied at a one-inch lever arm (about 0.113 N·m). Inch-pounds are used for small-fastener applications: computer assembly, firearms receivers, small-engine carburetor screws, and precision instrument assembly. A typical torque range for 1/4-20 machine screws is 60–80 in·lbf. US-made small torque wrenches and drivers are calibrated in in·lbf, often alongside N·cm or N·m.
