Mach 2.2 refers to 2.2 times the speed of sound. The speed of sound is variable, depending on pressure and temperature. The speed of sound on a standard day at sea level is approximately 762 miles per hour. Mach 2.2 on a standard day at sea level would be approximately 1676.4 miles per hour, or 27.94 miles per minute, or approximately half a mile per second.
Mach 6 is about 4,449.3 mph
Mach 0.8 = about 593.2 mph
Mach 3.5 is about 2,595.4 mph
Mach number is dependent on a number of factors. Factors such as air density or altitude will change the Mach number. At approximatively 45 000 ft Mach 0.85 =289.2361 m/s = 1041.25 km/h = 647.0028 mph
Maximum speed: Mach 2.5+ (1,650+ mph, 2,660+ km/h)
