Mach Number Calculator is a free online tool that displays the Mach number. BYJU’S online Mach number calculator tool makes the calculation faster, and it displays the Mach number in the surrounding medium in a fraction of seconds.

## How to Use the Mach Number Calculator?

The procedure to use the Mach number calculator is as follows:

Step 1: Enter the flow velocity, speed of sound, and x for the unknown value in the input field

Step 2: Now click the button “Calculate x” to get the Mach number

Step 3: Finally, the Mach Number in the surrounding medium will be displayed in the output field

### What is Meant by the Mach Number?

In Physics, Mach number is a dimensionless quantity. It is defined as the ratio of flow velocity and speed of sound in the surrounding medium. The Mach number formula is given by:

Mach Number, M = u/c

Where

“u” is the local flow velocity.

“c” is the speed of sound in the medium.

The Mach number can be classified into different types, namely:

• Subsonic
• Transonic
• Supersonic
• Hypersonic
• High-hypersonic
• Re-entry speeds
