How to Convert Mach Number to Centimeters per Second

To convert a Mach measurement to a centimeter per second measurement, multiply the Mach number by the conversion ratio. Mach 1 is equal to 34,300 centimeters per second, so use this simple formula to convert:

centimeters per second = Mach number × 34,300

The speed in centimeters per second is equal to the Mach number multiplied by 34,300.

For example, here's how to convert Mach 2 to centimeters per second using the formula above.
Mach 2 = (2 × 34,300) = 68,600 cm/s

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

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.[1]

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

What Are Centimeters per Second?

Centimeters per second are a measurement of speed expressing the distance traveled in centimeters in one second.

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.

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.[2] For example, cm/s is expressing a change in length or distance relative to a change in time.

Centimeters per second can be expressed using the formula:
vm/s = dcm / tsec

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