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

To convert a foot per second measurement to a speed of light measurement, multiply the speed by the conversion ratio. One foot per second is equal to 1.0167E-9 speed of light, so use this simple formula to convert:

The speed in speed of light is equal to the 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.

Feet per second and speed of light 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.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[1]}

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.

## 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.
