About thermo_style norm yes

Dear Users,
I'm puzzled by the 'norm' keyword in thermo_style. As energy is extensive and its unit is kcal/mole, why is there still an option for norm? I guess with 'norm no' in real unit, the output energy divided by the number of atoms in the system is what we usually talk about. With 'norm yes', one don't have to postprocessing the output. Am I right?

Best regards,
Fan

Dear Users,

Because energy is *not* extensive.

I guess with 'norm no' in real unit, the output energy divided by
the number of atoms in the system is what we usually talk about. With
'norm yes', one don't have to postprocessing the output. Am I right?

I don't see the relation between normalization of output properties and the need for postprocessing.
