## How to Convert Speed of Light to Kilometers per Hour

To convert a measurement in speed of light to a measurement in kilometers per hour, multiply the speed by the following conversion ratio: 1,079,252,848.7999 kilometers per hour/speed of light.

Since one speed of light is equal to 1,079,252,848.7999 kilometers per hour, you can use this simple formula to convert:

The speed in kilometers per hour is equal to the speed in speed of light multiplied by 1,079,252,848.7999.

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

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

## 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.^{[1]}

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

## What Are Kilometers per Hour?

Kilometers per hour are a measurement of speed expressing the distance traveled in kilometers in one hour.

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

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.^{[2]} For example, km/h is expressing a change in length or distance relative to a change in time.

Kilometers per hour can be expressed using the formula:

v_{km/h} = d_{km} / t_{hr}

The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.
