How to Convert Feet per Second to Speed of Light
To convert a measurement in feet per second to a measurement in speed of light, multiply the speed by the following conversion ratio: 1.0167E-9 speed of light/foot per second.
Since one foot per second is equal to 1.0167E-9 speed of light, you can use this simple formula to convert:
speed of light = feet per second × 1.0167E-9
The speed in speed of light is equal to the speed in feet per second multiplied by 1.0167E-9.
For example, here's how to convert 500,000,000 feet per second to speed of light using the formula above.
speed of light = (500,000,000 ft/s × 1.0167E-9) = 0.508352 c
Feet per second and speed of light are both units used to measure speed. Keep reading to learn more about each unit of measure.
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.[1] 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.

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.[2]
Speed of light can be abbreviated as c; for example, 1 speed of light can be written as 1 c.
