About Gram square metres

The gram square metre (g·m²) equals 10⁻³ kg·m², used for very light rotors with large radii. Lightweight UAV propeller blades, model aircraft propellers, and thin foam circular discs are characterised in g·m²; it bridges g·cm² and kg·m² in laboratory-scale spinning experiments. 1 g·m² = 10⁻³ kg·m² = 10 kg·cm² = 10 000 g·cm².

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.
