How to Convert Speed Of Sound to Mach Number

Speedometers are used in vehicles to measure speed

To convert a speed of sound measurement to a Mach measurement, multiply the speed by the conversion ratio. One speed of sound is equal to Mach 1, so use this simple formula to convert:

Mach number = speed of sound × 1

The Mach number is equal to the speed in speed of sound multiplied by 1.

For example, here's how to convert 5 speed of sound to Mach number using the formula above.
5 sound = (5 × 1) = Mach 5

Speed of sound and Mach number are both units used to measure speed. Keep reading to learn more about each unit of measure.

Speed Of Sound

The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343 meters per second, or roughly 767 miles per hour.

Speed of sound can be abbreviated as sound, for example 1 speed of sound can be written as 1 sound.

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
