It's just an incorrect label. The code writes kJ/mol as the units for 
all ordinate (i.e. Y-axis) quantities since nobody's troubled to write a 
mechanism to fix it. You can edit the .xvg file by hand with a text 
editor to make it look right. g_energy -xvgr allows you to pass in 
additional lines for output, but I don't know if that will allow you to 
do anything useful here.

The units are probably kg m^-3
