Explanation

Light travels at approximately 186,282 miles per second in a vacuum, which is about 299,792 kilometers per second. This fundamental constant is one of the most important values in physics. The other time units would give vastly different speeds - per hour would be 670 million mph, per minute would be even larger, and per year would be the distance of one light-year.
