Here is a a simple formular for speed of sound in metric or english units

Kelvin (Centigrade) Tk=Tc+273
Kelvin (Fahrenheit) Tkf=273+5/9*(Tf-32)

Speed of Sound (meters/sec) Deg Centigrade) =20.1*(SQRT(Tc+273))

Speed of Sound (feet/sec) Deg Fahrenheit
=20.1*(SQRT((5/8*(Tf-32)+273))*3.28083 (conversion from m/sec to ft/sec)

Temp Meters/Sec         Feet/Sec
59F    341.1083112     1119.12
100C     388.1954791     1273.60
212F     388.1954791     1273.60
