About these units
Mach (Mach)
The Mach number compares a speed with the speed of sound, which changes with air temperature. This converter uses 343 m/s (dry air at 20 °C), so Mach 1 is about 1,235 km/h or 767 mph.
Miles per hour (mph)
The mile per hour is used on road signs in the United Kingdom, the United States and a few other countries. A mile is exactly 1,609.344 meters, so 1 mph is 1.609344 km/h.
