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 Newton-meter (N·m)
The SI unit of torque (moment of force), equal to the twisting effect of one newton applied at the end of a one-meter lever. Newton-meters are the universal engineering unit for tightening specifications on bolts and fasteners, automobile engine output (a typical compact car: 150–300 N·m), and electric motor ratings. Virtually all modern torque wrenches display N·m as at least one of their units, and international service manuals specify fastener torque in N·m.
