About Tonne square metres

The tonne square metre (t·m²) equals 1000 kg·m², used for large industrial rotors and heavy rotating machinery. A 60-tonne paper-machine calendar roll of 0.5 m radius has I ≈7.5 t·m²; synchronous hydro-generator rotors: 50-2000 t·m²; large marine propulsion shafts: 5-50 t·m². 1 t·m² = 1000 kg·m² ≈737.6 slug·ft² ≈23 730 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.
