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.

About Litres per kilogram

The litre per kilogram (L/kg) equals 10⁻³ m³/kg, coincidentally equal to cm³/g. Process engineers prefer L/kg when working with liquids: specific volume of liquid oxygen at −183°C = 0.876 L/kg; liquid hydrogen = 14.1 L/kg. HVAC refrigerant datasheets and cryogenic transfer calculations typically give specific volume in L/kg. 1 L/kg = 10⁻³ m³/kg = 1 cm³/g.
