Enter the value in feet per second to get the conversion in mach (speeds of sound):
The foot per second is derived from the foot per hour by multiplying by 3600. 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.
