Air - Speed of Sound vs. Temperature

Speed of sound in air at standard atmospheric pressure with temperatures ranging -40 to 1000 °C (-40 to 1500 °F) - Imperial and SI Units.

Speed of Sound in Air Calculator

Calculate the speed of sound in air based on temperature using the following formulas:

SI Units (Metric):

  • Formula: v = 20.05 × √(273.16 + t)
  • Where: v = velocity of sound (m/s), t = temperature (°C)

Imperial Units (BG):

  • Formula: v = 49.03 × √(459.7 + t)
  • Where: v = velocity of sound (ft/s), t = temperature (°F)
