In the equation a=sqrt(gamma*R*T), for air,where a is the speed of sound, what is the value of R in ENGLISH UNITS? Thanks

After checking one of my aerodynamics textbooks... R=1716 (ft^2/(s^2 x degree_R).

I hope this helps!

How about learning to convert the units back and forth if you're going to stick with imperial units? If you're having problems with unit conversions I'd wait with aerodynamics...

I did the problem already by converting to metric and converting back...I just wanted to check by doing it straightforward in English units...BTW thanks Nick
