Conversion Formula

kg·dm² = g·mm² × 1.000000000e-7

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 decimetres

The kilogram square decimetre (kg·dm²) equals 10⁻² kg·m², occasionally used in SI-metric flywheel and rotor analysis when the decimetre is a convenient length scale. Lathe chuck jaws, grinding wheel flanges, and small centrifuges fall in the 0.1-10 kg·dm² range. 1 kg·dm² = 10⁻² kg·m² = 100 kg·cm² = 10 g·m².
