About the specific volume converter

Convert specific volume between m³/kg, L/kg, ft³/lb, and gallons per pound. Specific volume is the reciprocal of density — the volume occupied per unit mass. It is widely used in thermodynamics, particularly for steam tables and gas calculations.

Frequently asked questions

  • What is the relationship between specific volume and density?

    Specific volume v = 1/ρ, where ρ is density. Water at 4 °C has ρ = 1,000 kg/m³ and v = 0.001 m³/kg.

  • How many m³/kg is 1 ft³/lb?

    Approximately 0.0624 m³/kg.

  • Why is specific volume used in thermodynamics?

    Steam tables and ideal-gas law calculations are usually mass-specific. Working with v = 1/ρ makes per-mass property tables direct.

  • What is the SI unit of specific volume?

    The cubic meter per kilogram (m³/kg).
