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.
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.
