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.

About Cubic metres per kilogram

The cubic metre per kilogram (m³/kg) is the SI coherent derived unit of specific volume - the reciprocal of density. In steam and refrigerant thermodynamics, m³/kg appears in state tables: water at 100°C, 0.1 MPa has specific volume 1.674 m³/kg (vapour) and 1.044 × 10⁻³ m³/kg (liquid). The specific gas constant and molar volume calculations use m³/kg. 1 m³/kg = 1000 L/kg = 1000 cm³/g.
