Enter the value in meters per second to get the conversion into mach (speeds of sound):

The meter per second is the unit of speed in the International System. It is the speed needed to cover one meter in one 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.
