🧪 Thermodynamics & Fluid Density
Specific Volume Converter
Convert thermodynamic specific volume ($v = V/m = 1/\rho$) across SI ($\text{m}^3/\text{kg}, \text{L/kg}$), imperial ($\text{ft}^3/\text{lb}, \text{gal/lb}$), and CGS ($\text{cm}^3/\text{g}$) units.

♨️ Steam at 100°C (1.673 m³/kg)
💨 Air at STP (0.833 m³/kg)
🌡️ Liquid Mercury
Input Specific Volume
Standard Imperial (ft³/lb)
26.80 ft³/lb
m³/kg
1.673 m³/kg
Liters / kg
1,673 L/kg
Equivalent Density
0.598 kg/m³
💡 Reciprocal Density Relation:
$$v = \frac{1}{\rho} \implies 1.673\text{ m}^3/\text{kg} = 26.80\text{ ft}^3/\text{lb} = 1,673\text{ L/kg} = 1,673\text{ cm}^3/\text{g}$$
Understanding Specific Volume
Specific volume ($v$) is an intensive thermodynamic property defined as the volume occupied by a unit mass of a substance:
- Relationship with Density: $$v = \frac{V}{m} = \frac{1}{\rho}$$
- Steam Tables: In boiler and turbine thermodynamics, $v_f$ and $v_g$ represent the saturated liquid and vapor specific volumes.
- Conversion Factor: $1\text{ m}^3/\text{kg} = 16.01846\text{ ft}^3/\text{lb} = 1,000\text{ L/kg} = 1,000\text{ cm}^3/\text{g}$.
