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 feet per pound
The cubic foot per pound (ft³/lb) equals 0.028316846592 / 0.45359237 ≈0.062428 m³/kg, standard in US power-plant and HVAC engineering. ASHRAE psychrometric charts express humid-air specific volume in ft³/lb; Spirax Sarco steam tables in US customary units list specific volume in ft³/lb. Sea-level atmospheric air ≈1.205 kg/m³ corresponds to ≈0.835 ft³/lb. 1 ft³/lb ≈0.062428 m³/kg ≈62.43 L/kg.
