About Gram square centimetres

The gram square centimetre (g·cm²) equals 10⁻⁷ kg·m², the dominant unit in small electric motor and servo motor catalogues. Maxon RE-series micromotors list rotor inertia from 0.1-10 g·cm²; stepper motors for 3D printers range 50-500 g·cm². Clockmaking and watch-movement analysis use g·cm² for balance-wheel inertia calculations. 1 g·cm² = 10⁻⁷ kg·m² = 0.01 kg·mm².

About Pound square feet

The pound square foot (lb·ft²) equals ≈0.04214 kg·m², the dominant imperial unit for machine and vehicle rotational inertias. Aircraft control-surface counterbalancing, propeller blade inertia, and turbocharger rotor dynamics are specified in lb·ft²; steam turbine discs and helicopter tail-rotor assemblies: 1-10 000 lb·ft². 1 lb·ft² ≈0.04214 kg·m² = 144 lb·in² ≈0.03108 slug·ft².
