About Inch-pound-force (in·lbf)
An imperial unit of torque equal to one pound-force applied at a one-inch lever arm (≈ 0.112985 N·m per NIST SP 811 — exactly 1/12 of a ft·lbf). Inch-pounds are the standard US unit for small-fastener torque applications where ft·lbf would give awkwardly small decimal values: precision computer-assembly screws (M2-M5 fasteners typically 4-25 in·lbf), firearms receivers and optic mounting (Picatinny rail screws 15-65 in·lbf depending on size, scope-ring screws 18-22 in·lbf), small-engine carburetor and intake-manifold screws, precision-instrument assembly (laboratory benchtop devices, medical-device sub-assemblies), aerospace small-fastener torque tables in NASM 33540, and #6-#10 machine screws (60-80 in·lbf for 1/4-20 stainless per Industrial Fastener Institute recommendations). US-made small torque wrenches and 1/4-inch drive click drivers are calibrated in in·lbf, often dual-scale with N·cm or sub-N·m scales. Convert in·lbf to N·m by multiplying by 0.113; to ft·lbf by dividing 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.

Understanding Inch-pounds-force
The Inch-pound-force (symbol: in·lbf) is a unit of torque. An imperial unit of torque equal to one pound-force applied at a one-inch lever arm (≈ 0.112985 N·m per NIST SP 811 — exactly 1/12 of a ft·lbf). Inch-pounds are the standard US unit for small-fastener torque applications where ft·lbf would give awkwardly small decimal values: precision computer-assembly screws (M2-M5 fasteners typically 4-25 in·lbf), firearms receivers and optic mounting (Picatinny rail screws 15-65 in·lbf depending on size, scope-ring screws 18-22 in·lbf), small-engine carburetor and intake-manifold screws, precision-instrument assembly (laboratory benchtop devices, medical-device sub-assemblies), aerospace small-fastener torque tables in NASM 33540, and #6-#10 machine screws (60-80 in·lbf for 1/4-20 stainless per Industrial Fastener Institute recommendations). US-made small torque wrenches and 1/4-inch drive click drivers are calibrated in in·lbf, often dual-scale with N·cm or sub-N·m scales. Convert in·lbf to N·m by multiplying by 0.113; to ft·lbf by dividing by 12.
