The speed represented by Mach is not a constant; it is dependent on temperature and atmospheric composition.

Mach number is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance.

At a temperature of 15 oC and at sea level, the speed of sound is 761.2 mph.
