Mach Number to Meters Per Second Conversion
Enter the Mach number below to convert the speed to meters per second.
How to Convert Mach Number to Meters Per Second
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:
The speed in meters per second is equal to the Mach number multiplied by 343.
Mach number and meters per second are both units used to measure speed. Keep reading to learn more about each unit of measure.
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|
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 formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.
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.
