Converting from Light Year (ly) to Astronomical Unit (AU) | Astronomy distance

What is Light Year (ly)

A Light Year (ly) is a unit of astronomical distance, representing the distance that light travels in one year in the vacuum of space. Light travels at a speed of approximately 299,792 kilometers per second, and in one year, it covers a distance of about 9.461 trillion kilometers.

What is Astronomical Unit (AU)

An Astronomical Unit (AU) is a unit of length used in astronomy to describe the average distance from the Earth to the Sun, which is approximately 149.6 million kilometers. It is often used to measure distances within our solar system.
