About Gram square centimetres

The gram square centimetre (g·cm²) equals 10⁻⁷ kg·m², the dominant unit in small electric motor and servo motor catalogues. Maxon RE-series micromotors list rotor inertia from 0.1-10 g·cm²; stepper motors for 3D printers range 50-500 g·cm². Clockmaking and watch-movement analysis use g·cm² for balance-wheel inertia calculations. 1 g·cm² = 10⁻⁷ kg·m² = 0.01 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.
