About Pound-foot squared (lb·ft²)

An imperial mass-moment-of-inertia unit used in US mechanical engineering for flywheels, turbine rotors, and automotive drivetrain inertia. A typical passenger-car engine crankshaft+flywheel combined inertia is ~0.2 lb·ft² = 0.0084 kg·m². US automotive powertrain engineering specifications often list inertia in lb·ft².

About Kilogram-centimeter squared (kg·cm²)

A mass-moment-of-inertia unit equal to 10⁻⁴ kg·m². Used for small rotating components — electric motor rotors, servo shafts, small flywheels, and MEMS devices — where typical values fall in a range awkwardly small when quoted in kg·m². Motor and servo datasheets from Asian manufacturers often list rotor inertia in kg·cm².
