How to convert specific volume
Specific volume is volume per unit of mass, the inverse of density. It is used for steam and gases in thermodynamics.
Every specific volume unit is a fixed multiple of one base unit, the m³/kg. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert ft³/lb to m³/kg, multiply by 0.06242796058. To go the other way, divide by 0.06242796058.
The converter above does this for you and shows the exact formula under the result.
