The Speed of Sound calculator computes the speed of sound based on stiffness and density.

INSTRUCTIONS:  Choose units and enter the following:

  • (Ks) This is the coefficient of stiffness (Bulk Modulus for gases)
  • (ρ) This is the density of medium

Speed of Sound (c):  The calculator returns the velocity in meters per second.  However this can be automatically converted to compatible unit via the pull-down menu.

The Math / Science

The formula for the speed of sound is:

    `c = sqrt( K_s / ρ)`

where:

  • c is the speed of soundof sound in the medium
  • Ks is the coefficient of stiffness
  • ρ is the density of material

The Speed of Sound in dry air is 343.2 meters  per second.
