About Cubic inches per pound
The cubic inch per pound (in³/lb) equals 1.6387064 × 10⁻⁵ / 0.45359237 ≈ 3.6127 × 10⁻⁵ m³/kg. US aerospace propellant tables and legacy NACA compressible-flow charts list gas specific volumes in in³/lb; pre-metric Mollier charts for steam plotted enthalpy vs. in³/lb. 1 in³/lb ≈3.6127 × 10⁻⁵ m³/kg ≈0.03613 cm³/g.
About Cubic feet per slug
The cubic foot per slug (ft³/slug) equals 0.028316846592 / (0.45359237 × 9.80665 / 0.3048) ≈1.940 × 10⁻³ m³/kg, the natural specific-volume unit in US customary aerodynamics where mass is in slugs. The USAF Standard Atmosphere and pre-SI textbooks (Anderson, Shevell) give air specific volume in ft³/slug. 1 ft³/slug ≈1.940 × 10⁻³ m³/kg.
