About Slug square feet

The slug square foot (slug·ft²) equals ≈1.3558 kg·m², the fundamental moment of inertia unit in US customary aerodynamics and spacecraft attitude dynamics. Pre-SI spacecraft inertia tensors are tabulated in slug·ft² - NASA Apollo CSM principal moments ranged 12 000-90 000 slug·ft². USAF flight manuals and NACA stability reports use slug·ft². 1 slug·ft² ≈1.3558 kg·m² = 32.174 lb·ft².

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.
