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

To convert a kilometer per second measurement to a speed of light measurement, multiply the speed by the conversion ratio. One kilometer per second is equal to 3.3356E-6 speed of light, so use this simple formula to convert:

The speed in speed of light is equal to the kilometers per second multiplied by 3.3356E-6.

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

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

## 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.

## 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.
