Mach I (the Speed of Sound) is approximately 1,236 km/h (738 mp/h).
This is dependent on the air pressure. At sea level, the speed of sound is about 760 mph; at high altitude it reduces closer to 600 mph.
mach 2 is 1050 kmh. what is the speed in mph?
The KPH for Mach depends a bit on air pressure, temperature etc, but it's a little over 1000 KPH.
Mach2 is 2,450.088 kilometers per hour.
