The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 299 792 458 m (approximately 983 571 055 ft or 186 282 miles).
A light second is the distance that light travels in one second. It is exactly 299,792.458 kilometers or about 186,000 miles.
A light-second is a unit of length equal to the distance light in empty space travels in one second, and is exactly 299,792,458 meters. [1] The light-second is used in telecommunications, astronomy, and physics.
