I put this into Google search: "Convert mach 6 to mph"
Answer: mach 6 = 4,567.2423 mph
To be more percise, "mach" is a relative term and depends on
conditions. Mach is a number indicating the ratio of the speed of an
object to the speed of sound in the medium through which the object is
moving.

Mach is a measurement of the speed of sound in air. Therefore, mach6 is
six times the speed of sound in air. 761.2 * 6 = 4,567.2 mph. Mach" is
a relative measurement.
