Convert Gram square metres to Kilogram square millimetres
Convert Gram square metres (g·m²) to Kilogram square millimetres (kg·mm²) instantly and accurately.
Conversion Formula
kg·mm² = g·m² × 1000
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 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.
