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.
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.
