Conversion Formula
$$\tau_{\text{in·lbf}} = \tau_{\text{ft·lbf}} \times 12$$
Multiply the torque in foot-pounds by 12 to get inch-pounds.

ft·lbf to in·lbf in Engineering
Torque conversions are essential for mechanical design, automotive engineering, fastener specifications, and rotating machinery. US engineers use ft-lbf and in-lbf while international standards use N-m.
Foot-pound: Primary US customary torque unit. Used for engine torque, structural moments, and bolt torque specifications.
Inch-pound: Used for smaller fastener torque specifications, instrument calibration, and precision assembly.
