How to Convert Mach Number to Miles Per Hour

conversion scale showing Mach number and equivalent miles per hour speed values

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.

For example, here's how to convert Mach 2 to miles per hour using the formula above.
Mach 2 = (2 × 767.269148) = 1,534.538296 mph

Mach number and miles per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.

Mach Number

Mach, sometimes also referred to as a Mach number, is the ratio of the speed of an object to the speed of sound.

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 classifications for various mach numbers.
Speed Classification Mach Number
Subsonic Mach < 1.0
Transonic Mach = 1.0
Supersonic Mach > 1.0
Hypersonic Mach > 5.0

Miles Per Hour

Miles per hour are a measurement of speed expressing the distance travelled in miles in one 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 = dmithr

The velocity in miles per hour is equal to the distance in miles divided by time in hours.
