The mach number is a ratio between the aircraft's speed (v) and the speed of sound (a). Mach number equals object speed divided by speed of sound. Use this aerodynamics calculator to calculate the mach number for your aerodynamics problems.

Aircraft's Mach Number Calculation

Velocity (V) : [m/s]
Speed of sound (a) : [m/s]
Mach number (M) :

Formula:

M = V / a

where,
V - Velocity
a - Speed of sound

There are three important regions of Mach Numbers:

1. M < 1: Subsonic flow
2. M = 1: Sonic flow
3. M > 1: Supersonic flow
Mach regions and corresponding names
