How to Convert Mach to Meters Per Second

Speedometers are used in vehicles to measure speed

To convert a Mach measurement to a meter per second measurement, multiply the Mach number by the conversion ratio. Mach 1 is equal to 343 meters per second, so use this simple formula to convert:

meters per second = Mach number × 343

The speed in meters per second is equal to the Mach number multiplied by 343.

For example, here's how to convert Mach 2 to meters per second using the formula above.
Mach 2 = (2 × 343) = 686 m/s

Mach and meters per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

Mach

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

Meters Per Second

Meters per second are a measurement of speed expressing the distance travelled in meters in one second.

The meter per second, or metre per second, is the SI derived unit for speed in the metric system. Meters per second can be abbreviated as m/s, and are also sometimes abbreviated as m/sec. For example, 1 meter per second can be written as 1 m/s or 1 m/sec.

Meters per second can be expressed using the formula:
vm/s = dmtsec

The velocity in meters per second is equal to the distance in meters divided by time in seconds.
