Kilometers Per Second to Speed Of Light Conversion
Enter the speed in kilometers per second below to get the value converted to speed of light.
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.
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.
In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.[1]
Kilometers per second can be expressed using the formula:
vkm/s = dkmtsec
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. The definition of the speed of light is actually derived from the most recent 1983 international definition of the meter.[2]
Speed of light can be abbreviated as c, for example 1 speed of light can be written as 1 c.
