To convert a meter per second measurement to a Mach measurement, multiply the speed by the conversion ratio. One meter per second is equal to Mach 0.002915, so use this simple formula to convert:
Mach number = meters per second × 0.002915
The Mach number is equal to the speed in meters per second multiplied by 0.002915.
Meters per second and Mach number are both units used to measure speed. Keep reading to learn more about each unit of measure.
What Are Meters per Second?
Meters per second are a measurement of speed expressing the distance traveled 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.
In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[1] For example, m/s is expressing a change in length or distance relative to a change in time.
Meters per second can be expressed using the formula:
vm/s = dm / tsec
The velocity in meters per second is equal to the distance in meters divided by time in seconds.

What Is 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.[2]
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 |
