Meters Per Second to Mach Number Conversion
Enter the speed in meters per second below to get the value converted to Mach number.
How to Convert Meters Per Second to Mach Number
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:
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.
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.
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|
