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 Gram square centimetres

The gram square centimetre (g·cm²) equals 10⁻⁷ kg·m², the dominant unit in small electric motor and servo motor catalogues. Maxon RE-series micromotors list rotor inertia from 0.1-10 g·cm²; stepper motors for 3D printers range 50-500 g·cm². Clockmaking and watch-movement analysis use g·cm² for balance-wheel inertia calculations. 1 g·cm² = 10⁻⁷ kg·m² = 0.01 kg·mm².
