How to Convert Specific Volume Units
Specific volume is volume per unit mass, the reciprocal of density. The SI unit is cubic metre per kilogram (m³/kg); steam tables commonly list it in m³/kg or ft³/lb.
Every unit on this page is stored as a fixed factor relative to one reference unit, the cubic metre per kilogram (m³/kg). Converting is a two step multiply and divide:
- Multiply your value by the factor of the source unit to get the value in m³/kg.
- Divide that result by the factor of the target unit.
