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, derived from the standard acceleration of gravity g₀ = 9.80665 m/s²). Although officially replaced by the newton-meter under SI / ISO 80000-4, kgf·m persists in specific contexts: Japanese and older European machinery specifications (Yamaha, Suzuki, Kawasaki, and Honda motorcycle service manuals dual-list axle/swingarm/crankcase torques in kgf·m alongside N·m; Russian and Eastern-European industrial press ratings), Korean automotive heavy-equipment specs, legacy ISO 4759-3 fastener-tightening tables (now superseded by VDA / ISO 16047), and crank-handle / hand-tool torque ratings in markets where kgf is still the everyday force unit. Typical motorcycle axle nut: ~10 kgf·m ≈ 100 N·m. Convert kgf·m to N·m by multiplying by exactly 9.80665; to ft·lbf by multiplying by 7.233.
About Foot-pound-force (ft·lbf)
An imperial unit of torque equal to one pound-force applied at a one-foot lever arm (≈ 1.35582 N·m per NIST SP 811). Foot-pounds are the dominant US working unit for torque in automotive, industrial, and trades work: vehicle service manuals (passenger-car wheel-lug torque 80-100 ft·lbf; light-truck 130-160 ft·lbf; semi-truck 450-500 ft·lbf), automotive engine peak-torque specifications (US passenger cars typically 130-400 ft·lbf; full-size pickup diesel 800-1,000 ft·lbf; Dodge Challenger Hellcat Redeye 707 ft·lbf), US-made torque-wrench scales (Snap-On, Mac, Matco), helicopter and small-aircraft propeller/prop-strike inspection criteria, ASME B16 flange-bolt torque tables, and firearms barrel-threading specifications. Critical engineer's-eye distinction: ft·lbf as TORQUE (a vector moment) is dimensionally identical to ft·lb as ENERGY (a scalar work integral) — both are pound-force × foot — but they describe different physical quantities and must not be conflated when balancing power equations. Convert ft·lbf to N·m by multiplying by 1.356; to in·lbf by multiplying by 12.
