Temperature shows up as K, 0-255 and 0-40 values ?

Hello, 
I control my studio lights with a CS20.
I don't understand why the temperature controls are not the same from lights to lights ? 

for exemple : 
Cineroids and SL1 are controlled with 0-255 values.
Fiilex are controlled with 2800-6000K values.
Aputure 300X are controlled with 0-40 values.

Of course I understand where theses values come from, but is there a way to show all temperature parameters in Kelvin only ? Even if I have to map them myself ? 

Thank you all for your help.
