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 decimetres
The kilogram square decimetre (kg·dm²) equals 10⁻² kg·m², occasionally used in SI-metric flywheel and rotor analysis when the decimetre is a convenient length scale. Lathe chuck jaws, grinding wheel flanges, and small centrifuges fall in the 0.1-10 kg·dm² range. 1 kg·dm² = 10⁻² kg·m² = 100 kg·cm² = 10 g·m².
