Enter the value in kilometers per hour to get the conversion into mach (speeds of sound):
The kilometre per hour or km/h is a direct multiple of the meter per second. It is the speed needed to cover one kilometre in one hour. 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.
