Converting from Astronomical Unit (AU) to Light Second (ls) | Astronomy distance

What is Astronomical Unit (AU)

An Astronomical Unit (AU) is a unit of distance commonly used in astronomy to describe distances within the solar system. It is defined as the average distance between the Earth and the Sun, which is approximately 149.6 million kilometers or about 92.96 million miles.

What is Light Second (ls)

A Light Second (ls) is a unit of distance that represents the distance light travels in one second in a vacuum. Since the speed of light in a vacuum is constant at about 299,792 kilometers per second, one light second is equivalent to approximately 299,792 kilometers or about 186,282 miles.
