Specific Volume Converter
Specific volume is the volume occupied by one unit of mass — the reciprocal of density. The SI unit is the cubic meter per kilogram. Steam tables and psychrometric charts are built around it: saturated steam at atmospheric pressure occupies about 1.67 m³/kg, and dry air about 0.83 m³/kg.

Multiply the number of cubic meters per kilogram by 16.018463374 to get cubic feet per pound. How this is calculated
About specific volume conversion
Specific Volume conversion is commonly needed when steam tables, psychrometrics, and compressible-flow calculations. Specific volume is simply the reciprocal of density, so a value that rises means the substance is getting less dense.
