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.

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.

Understanding Newton-meters

The Newton-meter (symbol: N·m) is a unit of torque. 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).

Understanding Ounce-force-inches

The Ounce-force-inch (symbol: oz·in) is a unit of torque. 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).
