How to Convert Mach to Miles per Hour
Converting Mach (mach) to miles per hour (mph) involves using the speed of sound. Mach 1 is defined as the speed of sound, which is approximately 767.29 miles per hour at sea level and 20°C.
Formula
Miles per Hour = Mach × 767.29
or
mph = mach × 767.29
Step-by-step process
- Take the measurement in Mach
- Multiply that number by 767.29
- The result is the equivalent amount in miles per hour
Examples
- 1 mach = 767.29 mph
- 10 mach = 7672.9 mph
- 0.5 mach = 383.645 mph

Frequently Asked Questions
How many miles per hour are in one Mach?
One Mach is approximately 767.29 miles per hour (at sea level, 20°C).
Why is the conversion factor 767.29?
The speed of sound varies with temperature and medium. At sea level and 20°C, the speed of sound in dry air is approximately 343 meters per second. Since 1 mph = 0.44704 meters per second, then 343 / 0.44704 ≈ 767.29 mph.
