How to Convert Kilometers per Hour to Speed of Light
To convert a measurement in kilometers per hour to a measurement in speed of light, multiply the speed by the following conversion ratio: 9.2657E-10 speed of light/kilometer per hour.
Since one kilometer per hour is equal to 9.2657E-10 speed of light, you can 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 speed in kilometers per hour multiplied by 9.2657E-10.
Kilometers per hour and speed of light are both units used to measure speed. Keep reading to learn more about each unit of measure.
What Are Kilometers per 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. 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:
vkm/h = dkm / thr
The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.

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