In metric units, speed of light is exactly 299,792,458 metres per second or 1,079,252,848.8 kilometres per hour. Converted to imperial units, it is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour

Light travels in one year is
5.878 trillion miles
For example rotation of comet around the solar system it also the speed of comet or its.
There is same like speed of light that means the light travels 299,792 km/s only and always travels in straight line. There is no object that can go faster than speed of light.

The speed of light is roughly 186,000 miles per second or 300,000 kilometers per second.
Or, if you want it in mph and kph it is 669600000 mph and 1080000000 kph.
Also a light year (the distance light travels in 1 year) is 5865696000000 miles or 9460800000000.

The speed of light is the distance the light travels in some unit of time. (300,000,000 meters per second or 180,000 miles per second)

It depends on where the light is travelling.
In a vacuum with no gravity: 299 792 458 m / s
...as far as we can tell.

The other posters are correct. They gave you the speed of light in a vacuum. In other materials, it can go much slower. It can never go faster.

The other results are correct. Most science classes use 3 x 10^8 m/s.
