Question

what is the value of light velocity​

Answer 1

=> The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph.

=> The speed of light in free space (that is, in a vacuum) is a constant that has been measured to considerable accuracy. To nine significant figures, it is 299,792,458 meters per second (2.99792458 x 10 ^8 m/s).

=> On second thought 3x10^8 is the value of speed of light in vacuum(approx.) in m/s. The numerical value itself would change depending on the unit system one chooses to use. In fact c=1 in light speed units which is the unit generally employed by Relativists.
