The Mach Number calculator computes the mach number based on the velocity, density and bulk modulus.

INSTRUCTIONS: Choose units and enter the following:

  • (v) This is the velocity 
  • (ρ) This is the density
  • (E) This is the bulk modulus

Mach Number (M): The calculator returns mach number as a real number with no units.

The Mach Number is a dimensionless value useful for analyzing fluid flow dynamics problems where compressibility is a significant factor.  The formula for Mach Number based on the density and bulk modulus is:

      `M = v · sqrt(ρ / E)`
