Convert Tonne square metres to Gram square metres
Convert Tonne square metres (t·m²) to Gram square metres (g·m²) instantly and accurately.
Conversion Formula
g·m² = t·m² × 1000000
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 metres
The gram square metre (g·m²) equals 10⁻³ kg·m², used for very light rotors with large radii. Lightweight UAV propeller blades, model aircraft propellers, and thin foam circular discs are characterised in g·m²; it bridges g·cm² and kg·m² in laboratory-scale spinning experiments. 1 g·m² = 10⁻³ kg·m² = 10 kg·cm² = 10 000 g·cm².
