The velocity of sound can be calculated in metric units as
vms = 20.05 (273.16 + tC)1/2 (1)
vms = velocity of sound (m/s)
tC = temperature (°C)
Velocity of sound in Imperial units:
vfts = 49.03 (459.7 + tF)1/2 (2)
vfts = velocity of sound (ft/s)
tF = temperature (°F)
Note that speed is a scalar quantity. Velocity is vector quantity with direction.
