Speed of Sound in Air Calculator
Compute acoustic propagation velocity using Laplace's adiabatic formula: c = 331.3 × √(1 + T/273.15). Real-time Mach 1 conversion and temperature response.
Input Parameters
20.0 °C (68.0 °F)
Acoustic Physics Formula:
c ≈ 331.3 × √(1 + T / 273.15) [m/s]
Where T is Celsius temperature and c is phase velocity.
