The speed of light in a vacuum is about 299,792 kilometers per second, or approximately 186,282 miles per second.
"Meters per second" is a proper and wonderful unit for speed, but there's no answer to that question, because a 'light-year' is not a speed. It's a distance, defined as the distance that light travels through vacuum in one year.
