By this, i assume you mean: 

q = 1/2 rho U^2

instead of

q=  p(1+(γ-1)/2 M^2)^(γ/(γ-1)) - p

Also, in KSP, is Mach number calculated from (γ*R*T)^0.5 i.e. does it depend on temperature and atmospheric composition?

Yeah, I was going by the first method.

Mach is indeed calculated that way, each planet has its own molar mass and gamma, and density comes from that and temperature.

thanks for the answer!
