## How to Convert Speed Of Sound to Feet Per Second

To convert a speed of sound measurement to a foot per second measurement, multiply the speed by the conversion ratio. One speed of sound 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 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.

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

## 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.

## Feet Per Second

Feet per second are a measurement of speed expressing the distance travelled 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 formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[2]}

Feet per second can be expressed using the formula:

v_{ft/s} = d_{ft}t_{sec}

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