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 Kilogram square centimetres
The kilogram square centimetre (kg·cm²) equals 10⁻⁴ kg·m², the dominant unit in European servo and industrial drive engineering. ABB, Siemens, and Bosch Rexroth servo drive datasheets specify rotor and reflected load inertia in kg·cm²; IEC 61800 drive sizing balances motor-to-load inertia ratio in kg·cm². Industrial servomotors: 0.05-200 kg·cm². 1 kg·cm² = 10⁻⁴ kg·m² = 100 kg·mm².
