About Kilogram square millimetres
The kilogram square millimetre (kg·mm²) equals 10⁻⁶ kg·m², widely used in CAD software and precision mechanical engineering. SolidWorks, CATIA, and Siemens NX report mass moment of inertia in kg·mm² for gear blanks, pulley hubs, and precision spindle assemblies. Industrial small servo motor rotors: 100-10 000 kg·mm². 1 kg·mm² = 10⁻⁶ kg·m² = 10 g·cm² = 0.01 kg·cm².
About Pound square feet
The pound square foot (lb·ft²) equals ≈0.04214 kg·m², the dominant imperial unit for machine and vehicle rotational inertias. Aircraft control-surface counterbalancing, propeller blade inertia, and turbocharger rotor dynamics are specified in lb·ft²; steam turbine discs and helicopter tail-rotor assemblies: 1-10 000 lb·ft². 1 lb·ft² ≈0.04214 kg·m² = 144 lb·in² ≈0.03108 slug·ft².
