1 ly = 9.461e+12 km
Full precision:9.461e+12 km
Step-by-Step Solution

To convert 1 light years to kilometers, we multiply by 9.461e+12 because one light year equals exactly 9.461e+12 kilometers.

1 light year = 9.461e+12 kilometers

Since each light year contains 9.461e+12 kilometers, we multiply our value by this factor:

1 × 9.461e+12 = 9.461e+12 kilometers

So 1 light years = 9.461e+12 kilometers.

Quick check: 9.461e+12 ÷ 9.461e+12 = 1 light years
