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.
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.
