The speed of light in kilometers per hour is 10.8*10power8 km/h, or 1,079,252,848.8 kph.

Check the math:

Light travels at 299,792,458 meters per second. There are 1000 meters in a kilometer, so 299,792,458 mps becomes 299,792.458 kps. There are 60 seconds in a minute, 60 minutes in an hour, so:

299,792.458 x 60 = 17,987,547.48 kpm (kilometers per minute)

17,987,547.48 x 60 = 1,079,252,848.8 kph (kilometers per hour)

Speed of light c = 299792458 m/s × 1 km/1000 m = 299792.458 km/s.

Speed of light c = 299792.458 km/s × 3600 s/ 1 hr = 1079252848.8 km/hr.
