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.
About Kilogram-force-meter (kgf·m)
A legacy metric unit of torque equal to one kilogram-force applied at a one-meter lever arm (exactly 9.80665 N·m, derived from the standard acceleration of gravity g₀ = 9.80665 m/s²). Although officially replaced by the newton-meter under SI / ISO 80000-4, kgf·m persists in specific contexts: Japanese and older European machinery specifications (Yamaha, Suzuki, Kawasaki, and Honda motorcycle service manuals dual-list axle/swingarm/crankcase torques in kgf·m alongside N·m; Russian and Eastern-European industrial press ratings), Korean automotive heavy-equipment specs, legacy ISO 4759-3 fastener-tightening tables (now superseded by VDA / ISO 16047), and crank-handle / hand-tool torque ratings in markets where kgf is still the everyday force unit. Typical motorcycle axle nut: ~10 kgf·m ≈ 100 N·m. Convert kgf·m to N·m by multiplying by exactly 9.80665; to ft·lbf by multiplying by 7.233.
