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 Ounce square inches
The ounce square inch (oz·in²) equals ≈1.829 × 10⁻⁵ kg·m², used in US precision instrument engineering for light rotating components. Pre-metric American gyroscope gimbal assemblies and US MIL-SPEC instrument servo actuators cited inertia in oz·in²; NACA gyroscope test reports use oz·in² for small rotating elements. 1 oz·in² ≈1.829 × 10⁻⁵ kg·m² = 16 oz·in² per lb·in².
