Here you can convert the Speed unit Speed of light into the unit Kilometers per second and vice versa you can convert Kilometers per second into Speed of light. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result. With the following calculator you can also calculate any other Speed unit.
Info about "Speed of light"
Definition: If an object moves at the light speed for one second, it travels a distance of 299,792.458 km or about 300,000 km. This is the light speed that light travels in a vacuum.
This speed is also used to propagate radio signals, which is very important in space travel. For example, a signal from Mars takes about 3 to 20 minutes to reach Earth depending on its actual position. We notice a sunrise on earth about 8 minutes later because the light of the sun arrives to our eyes at that time.
Info about "Kilometers per second"
Kilometer per second is part of the metric system and it is derived from the standard unit of speed, meter per second (m/s). This is because both meters and seconds are defined as the basic units for length and time respectively.
This unit is defined as follows: An object moving at "1 km/s" per second will cover one kilometer. "km/s" is approved to use in the international system of units (SI).
