1 AU = 0 ly
Full precision:0.00001581 ly
Step-by-Step Solution
To convert 1 au to light years, we divide by 63241.08 because one light year equals exactly 63241.08 au.
1 light year = 63241.08 au
Since there are 63241.08 au in every light year, we divide our value by this factor:
1 ÷ 63241.08 = 0 light years
So 1 au = 0 light years.
Quick check: 0 × 63241.08 = 1 au
Example Conversions
Example 1: 1 AU = 0 ly
1 ÷ 63241.08 = 0
1 ÷ 63241.08 = 0
Example 2: 5 AU = 0.0001 ly
5 ÷ 63241.08 = 0.0001
5 ÷ 63241.08 = 0.0001
Example 3: 10 AU = 0.0002 ly
10 ÷ 63241.08 = 0.0002
10 ÷ 63241.08 = 0.0002
