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.
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.
