Conversion number between kilometre per hour [km/h] and speed of light [c] is 9.2656693110598 × 10-10. This means, that kilometre per hour is smaller unit than speed of light.
Switch to reverse conversion:
from speed of light to kilometre per hour conversion
| [km/h] |
Result in speed of light
?If conversion between kilometre per hour to metre-per-second and metre-per-second to speed of light is exactly definied, high precision conversion from kilometre per hour to speed of light is enabled.

Definition of kilometre per hour unit: ≡ 1 km / 3600 s. km/h in everyday life is the most commonly used speed unit (in Europe). Interpretation: The speed with which the body travels 1 kilometre in 1 hour. The number on traffic signs indicating speed limits is also in this unit of measure.
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.
