About Kilogram square metres
The kilogram square metre (kg·m²) is the SI coherent derived unit of moment of inertia. It defines the rotational analogue of mass in Newton's second law: τ = Iα (torque in N·m, angular acceleration in rad/s²). A solid disc of 10 kg and 0.5 m radius has I = 1.25 kg·m². Electric motor rotors: 0.001-10 kg·m². Wind turbine rotors: 10⁶-10⁸ kg·m². 1 kg·m² = 10 000 kg·cm² ≈0.7376 slug·ft².
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.
