To convert miles per hour to Mach, enter the value in the first field. The result in Mach is calculated automatically using the exact conversion factor.
1 mph ≈ 0.00131370301801 Mach
1 Mach ≈ 761.207050823 mph
Formula: Mach ≈ mph × 0.00131370301801
mph ≈ Mach × 761.207050823
Definitions: 1 mph = 0.44704 m/s; 1 Mach = 340.29 m/s
The mile per hour (mph) is used for road speed limits and vehicle speeds in the United States and the United Kingdom, and for baseball pitch speeds and wind speeds in the United States.
Mach is speed relative to the speed of sound. This converter uses Mach 1 = 340.29 m/s, the speed of sound in dry air at sea level and 15 °C (standard atmosphere); the real speed of sound changes with temperature and altitude, so the result is exact only under those conditions.
