Enter the Mach number and the speed of sound into the calculator to determine the velocity.

Mach Number to Velocity Formula

The following equation is used to calculate the Mach Number to Velocity.

V = M*c

  • Where V is the local velocity (m/s)
  • M is the Mach number
  • c is the speed of sound in the medium (m/s)

How to Convert Mach Number to Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate the velocity from Mach number.

First, determine the Mach number. In this example, the Mach number is found to be 3.25.

Next, determine the speed of sound in the medium. For this problem, the speed of sound in the medium is found to be 400 m/s.

Finally, calculate the velocity from the Mach number using the formula above:

V = M*c

V = 3.25 * 400

V =1300 m/s
