Centimeters Per Second to Mach Number Conversion
Enter the speed in centimeters per second below to get the value converted to Mach number.
How to Convert Centimeters Per Second to Mach Number
To convert a centimeter per second measurement to a Mach measurement, multiply the speed by the conversion ratio. One centimeter per second is equal to Mach 2.9155E-5, so use this simple formula to convert:
The Mach number is equal to the speed in centimeters per second multiplied by 2.9155E-5.
Centimeters per second and Mach number are both units used to measure speed. Keep reading to learn more about each unit of measure.
The centimeter per second, or centimetre per second, is an SI unit of speed in the metric system. Centimeters per second can be abbreviated as cm/s, and are also sometimes abbreviated as cm/sec. For example, 1 centimeter per second can be written as 1 cm/s or 1 cm/sec.
Centimeters per second can be expressed using the formula:
vm/s = dcmtsec
The velocity in centimeters per second is equal to the distance in centimeters 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|
