Convert astronomical units (AU) to light years (ly) with formulas, examples, and conversion tables.
To convert 1 astronomical units to light years, we divide by 63241.98 because one light year equals exactly 63241.98 astronomical units.
Since there are 63241.98 astronomical units in every light year, we divide our value by this factor:
So 1 astronomical units = 1.5812e-5 light years.
To convert astronomical units to light years, divide the value by 63241.98.
1 light year = 63241.98 astronomical units
