Reverse Factor

1 oz·in = 0.0624999 in·lbf

Worked Example

Convert 25 Inch-pounds-force to Ounce-force-inches: 25 in·lbf = 400.001 oz·in

About Inch-pound-force (in·lbf)

An imperial unit of torque equal to one pound-force applied at a one-inch lever arm (about 0.113 N·m). Inch-pounds are used for small-fastener applications: computer assembly, firearms receivers, small-engine carburetor screws, and precision instrument assembly. A typical torque range for 1/4-20 machine screws is 60–80 in·lbf. US-made small torque wrenches and drivers are calibrated in in·lbf, often alongside N·cm or N·m.

About Ounce-force-inch (oz·in)

An imperial unit of torque equal to one ounce-force at a one-inch lever arm (about 0.00706 N·m). Ounce-inches appear on US small-motor datasheets (fractional-horsepower DC motors, stepper motors, actuators), precision servo ratings, and instrument-grade mechanical equipment. At this scale, oz·in provides finer resolution than in·lbf for specifying startup torque and continuous-duty ratings of low-power motors.
