Inch-pounds specify small fasteners, electronics assembly torque, and precision instrument screws in US industry.
The foot-pound (ft·lbf) as torque is an imperial unit — the turning effect of a one-pound-force applied one foot from the axis. Same number as energy foot-pounds but a different physical quantity.
Foot-pounds rate US socket wrench settings, automotive lug-nut torque specs, and machinery manuals in customary units.
