How to Convert Kilometers Per Hour to Speed Of Light

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

To convert a kilometer per hour measurement to a speed of light measurement, multiply the speed by the conversion ratio. One kilometer per hour is equal to 9.2657E-10 speed of light, so use this simple formula to convert:

speed of light = kilometers per hour × 9.2657E-10

The speed in speed of light is equal to the kilometers per hour multiplied by 9.2657E-10.

For example, here's how to convert 5 kilometers per hour to speed of light using the formula above.
5 km/h = (5 × 9.2657E-10) = 4.6328E-9 c

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

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.

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.
