1 AU = 1.5812e-5 ly
Full precision:0.000015812 ly
Step-by-Step Solution
To convert 1 astronomical units to light years, we divide by 63241.98 because one light year equals exactly 63241.98 astronomical units.
1 light year = 63241.98 astronomical units
Since there are 63241.98 astronomical units in every light year, we divide our value by this factor:
1 ÷ 63241.98 = 1.5812e-5 light years
So 1 astronomical units = 1.5812e-5 light years.
Quick check: 1.5812e-5 × 63241.98 = 1 astronomical units
