Convert kilometers (km) to light years (ly) with formulas, examples, and conversion tables.
To convert 1 kilometers to light years, we divide by 9.46e+12 because one light year equals exactly 9.46e+12 kilometers.
Since there are 9.46e+12 kilometers in every light year, we divide our value by this factor:
So 1 kilometers = 1.06e-13 light years.
To convert kilometers to light years, divide the value by 9.46e+12.
1 light year = 9.46e+12 kilometers
