About Pound square inches
The pound square inch (lb·in²) equals ≈2.926 × 10⁻⁴ kg·m², the standard US customary unit for motor and machinery rotors. Rockwell Automation, Parker Hannifin, and Allied Motion servo sizing catalogs express rotor inertia in lb·in²; US machine-tool spindle and conveyor drive specifications use lb·in². High-speed spindle rotors: 5-50 lb·in². 1 lb·in² ≈2.926 × 10⁻⁴ kg·m² = 1/144 lb·ft².
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.
