there must be some h=1 constant ignored in the formula for the van der Waals term.
At the face value, if energy is C6/r^6, than for
C6=5.42E-24 and r=6 um I’d get
5.24e-24/(6e-6)^6=112MJ of energy.
And 1 MJ is approximately equal to the energy released by burning 0.24 gallons (or 0.9 liters) of gasoline.
