Mach number ((M)*) to Speed of sound in air (ssia) converter

Converting from Mach number ((M)*) to Speed of sound in air (ssia)

What is Mach number ((M)*)

The Mach number, represented as ((M)*), is the ratio of an object's speed to the speed of sound in the medium through which the object is traveling. For example, a Mach number of 2 indicates that the object is moving at twice the speed of sound.

What is Speed of sound in air (ssia)

The speed of sound in air (ssia) refers to the speed at which sound waves travel through the air. It is approximately 343 meters per second at room temperature and normal atmospheric pressure.

Conversion Formulas

The relationship between Mach number ((M)*) and speed of sound in air (ssia) can be expressed through the following formulas:

Examples

• 3 ((M)*) to (ssia):

  • Mach number ((M)*)=3
  • Speed of sound in air (ssia)=3433​=3∗100m/s

• 9 (ssia) to ((M)*):

  • Speed of sound in air (ssia)=9
  • Mach number ((M)*)=9∗343=9∗102((M)*)

• 15 ((M)*) to (ssia):

  • Mach number ((M)*)=15
  • Speed of sound in air (ssia)=34315​=1.5∗101m/s

By utilizing these conversion formulas, you can accurately convert between Mach numbers and the speed of sound in air. Remember that at Mach 1, the speed of an object is equal to the speed of sound in air.
