Van der Waals constants (data page)

The following table lists the Van der Waals constants (from the Van der Waals equation) for a number of common gases and volatile liquids.[1]

To convert from ${\displaystyle L^{2}bar/mol^{2}}$ to ${\displaystyle L^{2}kPa/mol^{2}}$, multiply by 100.
To convert from ${\displaystyle L^{2}bar/mol^{2}}$ to ${\displaystyle m^{6}Pa/mol^{2}}$, divide by 10.
To convert from ${\displaystyle L/mol}$ to ${\displaystyle m^{3}/mol}$, divide by 1000.
