Mach Number to Feet Per Second Conversion
Enter the Mach number below to convert the speed to feet per second.
How to Convert Mach Number to Feet Per Second
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:
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.
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 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.
Feet per second can be expressed using the formula:
vft/s = dfttsec
The velocity in feet per second is equal to the distance in feet divided by time in seconds.
