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industrial press ratings), Korean automotive heavy-equipment specs, legacy ISO 4759-3 fastener-tightening tables (now superseded by VDA / ISO 16047), and crank-handle / hand-tool torque ratings in markets where kgf is still the everyday force unit.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.
About Newton-meter (N·m)
The SI unit of torque, moment of force, and bending moment (ISO 80000-4 §4-10), equal to the twisting effect produced when one newton of force is applied at the end of a one-meter lever arm (1 N·m = 1 kg·m²/s²). N·m is dimensionally identical to the joule, but by convention torque uses N·m and energy uses J — never abbreviate torque as 'joules' even though the units are dimensionally equivalent. Newton-meters are the universal engineering unit for fastener-tightening specifications under VDA / ISO 16047 and DIN 946 (the German tightening-torque standard widely referenced internationally), automobile engine output (a typical compact car produces 150-300 N·m peak torque; a modern diesel truck 1,500-2,500 N·m; Bugatti Chiron 1,600 N·m), electric-motor torque ratings on the NEMA and IEC nameplates (a 1 kW industrial motor at 1,800 rpm produces ~5.3 N·m), bicycle drive-train measurement (e-bike pedal-assist torque sensors typically resolve 0.1 N·m), and finite-element bending-moment results in M_y / M_z form. Modern torque wrenches list N·m as the primary scale; international service manuals specify all fastener torques in N·m alongside the legacy unit.
