What is a foot-pound?
A foot-pound of torque is one pound-force applied one foot from the pivot, about 1.356 Nm. US fastener specifications and engine output figures use it. Some manuals write it lb-ft to distinguish torque from energy.
What is an inch-pound?
An inch-pound is one twelfth of a foot-pound, about 0.113 Nm. Small fasteners, electronics and aviation hardware are specified in inch-pounds because foot-pound figures would be inconveniently small.
