How to Convert Speed of Sound to Feet per Second

To convert a measurement in speed of sound to a measurement in feet per second, multiply the speed by the following conversion ratio: 1,125.328084 feet per second/speed of sound.

Since one speed of sound is equal to 1,125.328084 feet per second, you can use this simple formula to convert:

feet per second = speed of sound × 1,125.328084

The speed in feet per second is equal to the speed in speed of sound multiplied by 1,125.328084.

For example, here's how to convert 5 speed of sound to feet per second using the formula above.
feet per second = (5 sound × 1,125.328084) = 5,626.64042 ft/s

Speed of sound and feet per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

What Is the Speed of Sound?

The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343 meters per second,[1] or roughly 767 miles per hour.

Speed of sound can be abbreviated as sound; for example, 1 speed of sound can be written as 1 sound.

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.
