How to Convert Mach Number to Miles per Hour
To convert a Mach measurement to a mile per hour measurement, multiply the Mach number by the conversion ratio. Mach 1 is equal to 767.269148 miles per hour, so use this simple formula to convert:
miles per hour = Mach number × 767.269148
The speed in miles per hour is equal to the Mach number multiplied by 767.269148.
Mach number and miles per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.
What Is Mach Number?
Mach can be abbreviated as M, and is also sometimes abbreviated as Ma. For example, Mach 1 can be written as 1 M or 1 Ma.
Although Mach can be abbreviated M or Ma, the Mach number is typically expressed with the number after the unit name. For example, the expression Mach 3 is preferred rather than 3 Machs or 3 M.
The speed is classified as either subsonic, transonic, supersonic, or hypersonic depending on the Mach number.
|Speed Classification||Mach Number|
|Subsonic||Mach < 1.0|
|Transonic||Mach = 1.0|
|Supersonic||Mach > 1.0|
|Hypersonic||Mach > 5.0|

What Are Miles per Hour?
The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.
Miles per hour can be expressed using the formula:
vmph = dmi / thr
The velocity in miles per hour is equal to the distance in miles divided by time in hours.
