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 Cubic metres per tonne
The cubic metre per tonne (m³/t) equals 10⁻³ m³/kg, coincidentally equal to L/kg and cm³/g, preferred in bulk-material handling, geotechnical engineering, and quarrying. Swell factor tables for excavated rock list specific volume in m³/t: solid granite ≈0.37 m³/t, blasted rock ≈0.45 m³/t. International shipping designates cargo stowage factors in m³/t. 1 m³/t = 10⁻³ m³/kg = 1 L/kg.
