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.
About Ounce square inches
The ounce square inch (oz·in²) equals ≈1.829 × 10⁻⁵ kg·m², used in US precision instrument engineering for light rotating components. Pre-metric American gyroscope gimbal assemblies and US MIL-SPEC instrument servo actuators cited inertia in oz·in²; NACA gyroscope test reports use oz·in² for small rotating elements. 1 oz·in² ≈1.829 × 10⁻⁵ kg·m² = 16 oz·in² per lb·in².
