About Foot-pound-force (ft·lbf)
An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (≈ 1.35582 N·m per NIST SP 811). Foot-pounds are the dominant US working unit for torque in automotive, industrial, and trades work: vehicle service manuals (passenger-car wheel-lug torque 80-100 ft·lbf; light-truck 130-160 ft·lbf; semi-truck 450-500 ft·lbf), automotive engine peak-torque specifications (US passenger cars typically 130-400 ft·lbf; full-size pickup diesel 800-1,000 ft·lbf; Dodge Challenger Hellcat Redeye 707 ft·lbf), US-made torque-wrench scales (Snap-On, Mac, Matco), helicopter and small-aircraft propeller/prop-strike inspection criteria, ASME B16 flange-bolt torque tables, and firearms barrel-threading specifications. Critical engineer's-eye distinction: ft·lbf as TORQUE (a vector moment) is dimensionally identical to ft·lb as ENERGY (a scalar work integral) — both are pound-force × foot — but they describe different physical quantities and must not be conflated when balancing power equations. Convert ft·lbf to N·m by multiplying by 1.356; to in·lbf by multiplying by 12.
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.
