Mach number calculator

In flight mechanics and aerodynamics, the “Mach number” (often denoted as $M$) is a dimensionless parameter that represents the ratio of an aircraft’s velocity to the local speed of sound in the surrounding air. It is a crucial parameter used to describe an aircraft’s speed relative to the speed of sound and is used to categorize the aircraft’s flight regime.

M=V/a​

Where:

• $M$ is the Mach number.
• $V$ is the velocity of the aircraft.
• $a$ is the local speed of sound in the air.
