sqrt(gamma x R x T)
Okay gamma is the ratio of specific heat at constant pressure vs ratio of specific heat at constant volume. What are the formulae for specific heat at constant pressure and specific heat at constant volume?

To find the Greek Alphabet, Γοογλε ιτ !
I've already went online to find it...

no, I want you to answer my questions.
Which questions? I explained what the reason I was asking about the units of pressure because I was trying to convert the TAS figures for mach (sea-level) into IAS readings at altitude.

Jane Doh is almost certainly an anti-sciolist
Sciolist means an amateur, right?

You only need to know pressure altitude and then multiply by Mach Number to get the flight EAS.
Pressure altitude means the pressure at a given altitude?
