How to Convert Feet Per Second to Speed Of Sound

Speedometers are used in vehicles to measure speed

To convert a foot per second measurement to a speed of sound measurement, multiply the speed by the conversion ratio. One foot per second is equal to 0.000889 speed of sound, so use this simple formula to convert:

speed of sound = feet per second × 0.000889

The speed in speed of sound is equal to the feet per second multiplied by 0.000889.

For example, here's how to convert 5,000 feet per second to speed of sound using the formula above.
5,000 ft/s = (5,000 × 0.000889) = 4.443149 sound

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

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.

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.

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.
