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 Kilogram-force-meter (kgf·m)
A legacy metric unit of torque equal to one kilogram-force applied at a one-meter lever arm (exactly 9.80665 N·m). Though officially replaced by newton-meters in SI, kgf·m persists on older European machinery specifications, Japanese motorcycle service manuals, industrial press ratings, and some legacy automotive torque specs. Typical motorcycle axle torques are often quoted in both kgf·m and N·m in multi-language service documentation.
