About specific volume units
Specific volume is volume per unit mass, the inverse of density. Its SI unit is the cubic meter per kilogram (m³/kg). It is widely used in thermodynamics, for example in steam and refrigerant tables.
One liter per kilogram is exactly 0.001 m³/kg and equals one cm³/g. One ft³/lb is about 0.062428 m³/kg. To turn a density into a specific volume, take its reciprocal: water at about 1000 kg/m³ has a specific volume of about 0.001 m³/kg.
Frequently asked questions
- How do I convert ft³/lb to m³/kg?
- Multiply by about 0.062428. One m³/kg is about 16.018 ft³/lb.
- How is specific volume related to density?
- It is the reciprocal: specific volume = 1 ÷ density. A density of 500 kg/m³ is a specific volume of 0.002 m³/kg.
- How many cubic feet per pound are in one cubic meter per kilogram?
- One cubic meter per kilogram ≈ 16.01846337 ft³/lb (cubic feet per pound).
