Enter the value in speeds of light to get the conversion into mach (speeds of sound):
The speed of light is a physical constant, worth nearly 300,000 kilometers per second. The Mach number is a dimensionless number expressing the ratio of an object's speed to the speed of sound. Thus, one goes at Mach 1 when moving at the speed of sound, at Mach 2 when going twice as fast, etc.
