Convert Gram square metres to Gram square millimetres
Convert Gram square metres (g·m²) to Gram square millimetres (g·mm²) instantly and accurately.
Conversion Formula
g·mm² = g·m² × 1000000
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.
