What is the approximate speed of light in kilometer per second?"
kilogram per second is the approximate speed of light
around 300 thousand kilometers per second in vacuum or air
The speed of light is 186,000 miles per second in a vacuum.
The speed of light in a vacuum is approximately 299,792,458 meters per second.
The speed of light is 983,571,056 feet per second.
The speed of light in a vacuum is approximately 186,282 miles per second (299,792 kilometers per second). This speed is considered to be the fastest possible speed in the universe according to Einstein's theory of relativity.
In vacuum, the speed of light is -- 299,792,458 meters per second -- 186,282.397 miles per second. If you were to travel at the speed of light, you could go around the Earth's equator approximately 7.6 times in one second. (Flying in a typical passenger jet, at a ground speed of 500 mph, it would take 4 hours to cross the continental US.)
The speed of light is about 880 thousand timesfaster than the speed of sound.
