Convert Kilogram square centimetres to Gram square millimetres
Convert Kilogram square centimetres (kg·cm²) to Gram square millimetres (g·mm²) instantly and accurately.
Conversion Formula
g·mm² = kg·cm² × 100000
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 Gram square millimetres
The gram square millimetre (g·mm²) equals 10⁻⁹ kg·m², the natural unit for MEMS gyroscope resonators and micro-fabricated spinning structures. CubeSat reaction wheel rotors range 1-50 g·mm²; chip-scale IMU proof masses sit below 1 g·mm². Watchmaking balance wheels and miniature turbine blades also fall in this range. 1 g·mm² = 10⁻⁹ kg·m² = 0.01 g·cm².
