Convert Astronomical Units to Light Years

Enter the number of astronomical units to convert into light years. Easy AU to light years conversion.
1 Astronomical Unit =
1.5812507 x 10-5 Light Years
(rounded to 8 digits)
An astronomical unit is the average distance between the Earth and the Sun. Estimates of this distance have varied over time. It is now defined as exactly 149,597,870.7 kilometers.
A light year is the distance that light travels in one year. The year used by the International Astronomical Union is 365.25 days. Therefore a light year is exactly 9,460,730,472,580.8 kilometers.
