How to Convert Speed Of Light to Kilometers Per Hour

conversion scale showing speed of light and equivalent kilometers per hour speed values

To convert a speed of light measurement to a kilometer per hour measurement, multiply the speed by the conversion ratio. One speed of light is equal to 1,079,252,848.7999 kilometers per hour, so use this simple formula to convert:

kilometers per hour = speed of light × 1,079,252,848.7999

The speed in kilometers per hour is equal to the 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.
5 c = (5 × 1,079,252,848.7999) = 5,396,264,243.9996 km/h

Speed of light and kilometers per hour 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 Hour

Kilometers per hour are a measurement of speed expressing the distance travelled 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.

Kilometers per hour can be expressed using the formula:
vkm/s = dkmthr

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