Conversion Formula
t·m² = kg·cm² × 1.000000000e-7
About Kilogram square centimetres
The kilogram square centimetre (kg·cm²) equals 10⁻⁴ kg·m², the dominant unit in European servo and industrial drive engineering. ABB, Siemens, and Bosch Rexroth servo drive datasheets specify rotor and reflected load inertia in kg·cm²; IEC 61800 drive sizing balances motor-to-load inertia ratio in kg·cm². Industrial servomotors: 0.05-200 kg·cm². 1 kg·cm² = 10⁻⁴ kg·m² = 100 kg·mm².
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.
