Convert Ounce square inches to Slug square feet
Convert Ounce square inches (oz·in²) to Slug square feet (slug·ft²) instantly and accurately.
Conversion Formula
slug·ft² = oz·in² × 1.348999573e-5
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 Slug square feet
The slug square foot (slug·ft²) equals ≈1.3558 kg·m², the fundamental moment of inertia unit in US customary aerodynamics and spacecraft attitude dynamics. Pre-SI spacecraft inertia tensors are tabulated in slug·ft² - NASA Apollo CSM principal moments ranged 12 000-90 000 slug·ft². USAF flight manuals and NACA stability reports use slug·ft². 1 slug·ft² ≈1.3558 kg·m² = 32.174 lb·ft².
