Understanding Speed of Sound Conversion

How to Convert

To convert kilometers per second (km/s) to speed of sound (Mach), multiply the speed by 2.915452. This conversion factor is based on the speed of sound in air at 20°C (68°F), which is approximately 343 meters per second.

Formula

Speed of Sound = Kilometers per Second × 2.915452

Common Applications

  • Aerospace engineering and supersonic flight
  • Meteorology and atmospheric studies
  • Ballistics and projectile motion analysis
  • Shock wave research

Note: The speed of sound varies with temperature, pressure, and medium. This converter uses the standard speed of sound in air at sea level and 20°C.
