Specific Volume Converter — m³/kg to ft³/lb and More
Convert between 6 units of specific volume — m³/kg, cm³/g, L/kg, ft³/lb, ft³/slug, and in³/lb. Specific volume is the volume per unit mass of a substance — the reciprocal of density. Steam at 100°C and 1 atm has a specific volume of 1.673 m³/kg — 1,670× larger than liquid water. Used in steam engineering, refrigeration and thermodynamic cycle analysis.
About the Specific Volume Converter
Specific volume is the volume occupied per unit mass of a substance — the reciprocal of density. It is widely used in thermodynamics and HVAC engineering where steam tables and refrigerant property charts list specific volume to calculate pipe sizing, heat exchanger design, and compression ratios. The SI unit is m³/kg, while ft³/lb is common in US engineering practice.
- ›Specific volume of liquid water at 20 °C ≈ 0.001002 m³/kg (very dense)
- ›Specific volume of steam at 100 °C and 1 atm ≈ 1.673 m³/kg — 1,670× larger than liquid
- ›Refrigerants like R-134a have specific volumes listed in property tables for system design
- ›Specific volume × density = 1 (they are exact reciprocals)
