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 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.
