Convert Ounce square inches to Gram square metres
Convert Ounce square inches (oz·in²) to Gram square metres (g·m²) instantly and accurately.
Conversion Formula
g·m² = oz·in² × 0.01828997834
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.
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.
