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 Gram-centimeter squared (g·cm²)
A CGS mass-moment-of-inertia unit (= 10⁻⁷ kg·m²) used for very small components: instrument gyroscopes, watch escapements, precision indexing wheels, and MEMS resonators. Optical precision instruments from historical-era European manufacturers often specify rotor inertia in g·cm².
