pz1337 is on a distinguished road

please advise on the following problems, thanks a lot
(1) when i compare pressure measurements in atomospheric boundary law[Pa] from a wind tunnel to a simulation (scaled geometry). Do I need to convert them to the pressure coefficient for that first?

If yes - how to? I have the pressure difference to the ambient pressure, the same velocity and density in both cases - so no use of a dimensionless number - correct?

Thanks a lot!
