The speed of light, in vacuum, is exactly 299,792,458 metres per second or 299,792.458 kilometres per second. The values are exact because this is how a metre is defined.

The relationship between a kilometre and a mile is not exact, so it is not possible to give an exact figure for the speed in miles. It is approximately 186,282 miles per second.
