Mach Number From Temperature Calculator

The Mach number ($M$) is a dimensionless quantity that represents the ratio of the speed of an object (such as an aircraft) to the speed of sound in the surrounding medium. A Mach number less than 1 indicates subsonic speeds, while a Mach number greater than 1 signifies supersonic speeds. The formula to calculate Mach number is expressed as:

where:

• $M$ is the Mach number,
• $q$ is the dynamic pressure (in Pa),
• $\rho$ is the density (in kg/m³),
• $\gamma$ is the heat capacity ratio ,
• $R$ is the specific gas constant (in J/(kg·K)),
• $T$ is the temperature (in Kelvin,).
