Here you can convert the Speed unit Speed of sound into the unit Kilometers per second and vice versa you can convert Kilometers per second into Speed of sound. 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 sound"
Definition: If an object travels at the speed of sound in air at 20 degrees Celsius for one second, it travels a distance of 343 meters per second. Actually, it is equivalent to 1.234,8 km/h.
The speed of sound is often illustrated by an example of a thunderstorm: if lightning strikes within 3 seconds of the thunder sound, then the thunderstorm is about 1 kilometer away. Another example, in a 100-meter sprint, the starting shot is fired directly next to the starting blocks. Imagine, if the start shot was fired at the finish line, it would take about 0.3 seconds of time to hear the shot in the start blocks.
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).
