This is dimensionally wrong at least in the SI system. I have a Ph.D. in
physical oceanography and a bachelor in pure physics, and I'm going to
fight this heresy as strongly as I fought the "/lying parameterized
type/" thing. This line is totally unacceptable in SI, *absolutely no
excuse can make it acceptable*. Do you really want to go in this fight
for just an example?

I do not claim that Mayer is wrong. But I'm pretty sure that the
Boltzmann constant is somewhere in his equations, maybe implicitly. As I
can not read German, and can not verify by myself.

I do not accept this silly argument (except if we take it as "/be more
pedagogic/"). The fact that someone understand the Boltzmann constant or
not does not change anything to the laws of physics or mathematics. The
desire to make money can not be stronger than the fact that 2 + 2 = 4,
not 5. In this particular case, m3*K (your formula) is NOT equals to
kg*m2/s2 (energy).
