## How to Convert Speed of Light to Feet per Second

To convert a measurement in speed of light to a measurement in feet per second, multiply the speed by the following conversion ratio: 983,571,056.43045 feet per second/speed of light.

Since one speed of light is equal to 983,571,056.43045 feet per second, you can use this simple formula to convert:

feet per second = speed of light × 983,571,056.43045

The speed in feet per second is equal to the speed in speed of light multiplied by 983,571,056.43045.

For example, here's how to convert 5 speed of light to feet per second using the formula above.
feet per second = (5 c × 983,571,056.43045) = 4,917,855,282.1522 ft/s

Speed of light 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 Light?

The speed of light is equal to exactly 299,792,458 meters per second, or 670,616,629 miles per hour. The definition of the speed of light is actually derived from the most recent 1983 international definition of the meter.[1]

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

## 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.
