fassssst!
Depending on the medium in which it propagates.
I vacuum wiki says "c is exactly 299,792,458 metres per second (1,079,252,848.8 km/h)."

A postulate concerning the cause of motion and velocity of the motion would be as follows; The smaller the mass the faster it moves.The large the mass the slower it moves in space.
In a gravity field any mass structure moving toward the gravitational mass would increase in velocity in proportion to the Gravity power density of the Gravitational field.
Light being the smallest and densest mass in the Universe would be the fastest moving mass structure in the Universe.
The Speed of light as measure on earth relative to the solar system has been measured as 186 thousand miles per seconds.
However; in other parts of the time levels of space in the Universe ,there has be no exact determination of what the speed of light would be at those levels.

Mr. Krishna the speed of light is actually 3*10^8 m/sec or 3*10^10 cm/sec........ and if u have any related queries regarding this pls contact me and i will definitely help u in this issue........

what kind of light? And in what medium?
Light moves faster in vacuum and also wavelength of the light also matters.

3.0x10^8 m/s in a vacuum is a reasonably good value to use.
