How to Convert Mach Number to Feet per Second
Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. He holds several degrees and certifications.
To convert a Mach measurement to a foot per second measurement, multiply the Mach number by the conversion ratio. Mach 1 is equal to 1,125.328084 feet per second, so use this simple formula to convert:
feet per second = Mach number × 1,125.328084
The speed in feet per second is equal to the Mach number multiplied by 1,125.328084.
Mach number and feet 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 Classification | Mach Number |
|---|---|
| Subsonic | Mach < 1.0 |
| Transonic | Mach = 1.0 |
| Supersonic | Mach > 1.0 |
| Hypersonic | Mach > 5.0 |

What Are Feet per Second?
Feet per second are a measurement of speed expressing the distance traveled in feet in one second.
The foot per second is a US customary and imperial unit of speed. Feet per second can be abbreviated as ft/s, and are also sometimes abbreviated as ft/sec or fps. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps.
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, ft/s is expressing a change in length or distance relative to a change in time.
Feet per second can be expressed using the formula:
vft/s = dft / tsec
The velocity in feet per second is equal to the distance in feet divided by time in seconds.
