Conversion number between kilometre per second [km/s] and speed of light [c] is 3.3356409519815 × 10-6. This means, that kilometre per second is smaller unit than speed of light.
Switch to reverse conversion:
from speed of light to kilometre per second conversion
| [km/s] |
Result in speed of light
?If conversion between kilometre per second to metre-per-second and metre-per-second to speed of light is exactly definied, high precision conversion from kilometre per second to speed of light is enabled.

Definition of kilometre per second unit: ≡ 1 km / 1 s. The speed with which the body moves 1 km in 1 second. The Earth's circulation speed is about 30 km/s.
Definition of speed of light unit: ≡ 299 792 458 m/s. Light velocity (in vacuum) is one of the basic physical constants. Sign c (Latin celeritas = speed). Its value is exactly: 299792458 m/s. Example: electromagnetic waves propagation speed 1 c.
