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

To convert a speed of light measurement to a foot per second measurement, multiply the speed by the conversion ratio. One speed of light is equal to 983,571,056.43045 feet per second, so use this simple formula to convert:

The speed in feet per second is equal to the 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.

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

## 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.

## 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.
