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

To convert a speed of light measurement to a kilometer per second measurement, multiply the speed by the conversion ratio. One speed of light is equal to 299,792.458 kilometers per second, so use this simple formula to convert:

The speed in kilometers per second is equal to the speed of light multiplied by 299,792.458.

**For example,**here's how to convert 5 speed of light to kilometers per second using the formula above.

Speed of light and kilometers 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.

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

## Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance travelled in kilometers in one second.

The kilometer per second, or kilometre per second, is an SI unit of speed in the metric system. Kilometers per second can be abbreviated as *km/s*, and are also sometimes abbreviated as *km/sec*. For example, 1 kilometer per second can be written as 1 km/s or 1 km/sec.

Kilometers per second can be expressed using the formula:

v_{km/s} = d_{km}t_{sec}

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.
