About Foot-pound-force (ft·lbf)
An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (about 1.356 N·m). Foot-pounds are the dominant US torque unit — automotive service manuals, wheel-lug torque specs, US-made torque wrenches, and firearms barrel-threading all list ft·lbf. A typical car's lug nut spec is 80–100 ft·lbf. Careful: ft·lbf as torque should not be confused with ft·lb as energy (same name, different dimension).
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.
