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.
About Slug square inches
The slug square inch (slug·in²) equals ≈9.415 × 10⁻³ kg·m², used in US aerospace guidance and flight mechanics. Pre-metric inertial navigation unit (INU) test reports and NACA stability-derivative tables listed gyroscope platform inertia in slug·in²; US autopilot servo actuator sizing also uses slug·in². 1 slug·in² ≈9.415 × 10⁻³ kg·m² ≈32.17 lb·in².
