Velocity of sound in air Calculator

Calculates the speed of sound in air.

Velocity of sound in air
Temperature T
Heat capacity ratio k
    1.       air:1.403, He:1.66
Molecular mass M
    1. g/mol
    2.  air:28.966, He:4

Velocity of sound c
    2. m/s
    2. km/h
    2. kn
At 15 degrees C, the velocity of sound is about 340 m/s in air and 997 m/s in helium gas.
