About Kilonewton-meter (kN·m)
A metric unit of torque/moment equal to exactly 1,000 newton-meters. Kilonewton-meters are the working unit for large-scale rotational and structural loads: industrial steam and gas turbines (a typical 100 MW power-station turbine produces ~250-500 kN·m at the rotor), large marine diesel engines for ship propulsion (a Wärtsilä Sulzer RTA96-C two-stroke produces ~7,600 kN·m at 102 rpm — the highest sustained torque of any production engine), locomotive traction (~300-800 kN·m starting torque from electric/diesel-electric locomotives), wind-turbine main-shaft torque (a modern 5 MW onshore turbine ~3,800 kN·m, 15 MW offshore Haliade-X ~9,000 kN·m), and structural-bending moments on reinforced-concrete beams, prestressed bridge girders, and large steel plate girders per Eurocode 2 / Eurocode 3 design codes. ASCE 7 and AISC 360 also accept kN·m in dual-unit specifications. Convert kN·m to kip-ft by dividing by 1.356.
About Inch-pound-force (in·lbf)
An imperial unit of torque equal to one pound-force applied at a one-inch lever arm (≈ 0.112985 N·m per NIST SP 811 — exactly 1/12 of a ft·lbf). Inch-pounds are the standard US unit for small-fastener torque applications where ft·lbf would give awkwardly small decimal values: precision computer-assembly screws (M2-M5 fasteners typically 4-25 in·lbf), firearms receivers and optic mounting (Picatinny rail screws 15-65 in·lbf depending on size, scope-ring screws 18-22 in·lbf), small-engine carburetor and intake-manifold screws, precision-instrument assembly (laboratory benchtop devices, medical-device sub-assemblies), aerospace small-fastener torque tables in NASM 33540, and #6-#10 machine screws (60-80 in·lbf for 1/4-20 stainless per Industrial Fastener Institute recommendations). US-made small torque wrenches and 1/4-inch drive click drivers are calibrated in in·lbf, often dual-scale with N·cm or sub-N·m scales. Convert in·lbf to N·m by multiplying by 0.113; to ft·lbf by dividing by 12.
