Mach Number from Specific Heat Ratio Calculator

The Mach number () quantifies an object’s speed relative to the speed of sound. It is calculated as the ratio of the object’s velocity to the speed of sound in the surrounding medium. An increase in the heat capacity ratio raises the speed of sound, potentially decreasing the Mach number  as it becomes more influenced by compressibility effects in aerodynamics. The formula to Calculate Mach number as follows:

Where:

  • : Mach number.
  • : Ratio of specific heats.
  • : Mach number relative to a reference frame.
