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 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.
