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).
