The formula
mph = Ma × 761.207
Worked through with a real value: 10 Mach = 7612.07 miles per hour.
Going the other way: Ma = mph × 0.0013137, so 1 mile per hour = 0.0013137 Mach.
What each unit is
- Mach Ma
- The speed of sound in the surrounding air. The value used here is Mach 1 at standard sea level (15°C, 101.325 kPa), where it equals 340.29 metres per second — at higher altitudes and different temperatures, the speed of sound differs significantly.
- mile per hour mph
- How many miles are covered each hour, used for road speeds in the USA, UK, and a few other countries.
Where these come from
- 1 Mach = 340.29 meters per second
- 1 mile per hour = 0.44704 meters per second
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
