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industrial press ratings), Korean automotive heavy-equipment specs, legacy ISO 4759-3 fastener-tightening tables (now superseded by VDA / ISO 16047), and crank-handle / hand-tool torque ratings in markets where kgf is still the everyday force unit.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 Ounce-force-inch (oz·in)
An imperial unit of torque equal to one ounce-force at a one-inch lever arm (≈ 0.00706155 N·m, exactly 1/192 of a ft·lbf since 1 lb = 16 oz and 1 ft = 12 in). Ounce-inches are the US working unit for fractional-horsepower motor torque specifications under NEMA standards and stepper-motor data sheets: stepper motors (NEMA-11 16-25 oz·in, NEMA-17 30-90 oz·in, NEMA-23 60-300 oz·in, NEMA-34 300-1,200 oz·in), small DC and BLDC motors for robotics and electromechanical actuators, RC servos (a typical analog hobby servo is 30-80 oz·in; high-torque digital servos reach 600 oz·in), instrument-grade torque measurement (precision torque sensors and calibrators), and small-appliance / electromechanical device design (camera lens autofocus motors, optical-disc drive spindles, paper-feed motors in printers / ATMs / currency-counters). At this scale oz·in provides finer resolution than in·lbf for specifying startup torque and continuous-duty ratings. Convert oz·in to N·m by multiplying by 0.00706; to kgf·cm by multiplying by 0.072.
