Full precision:1.9025e-12 ly
Feet + Inches:2325004' 7.8"
Step-by-Step Solution
To convert 18 kilometers to light years, we divide by 9.461e+12 because one light year equals exactly 9.461e+12 kilometers.
1 light year = 9.461e+12 kilometers
Since there are 9.461e+12 kilometers in every light year, we divide our value by this factor:
18 ÷ 9.461e+12 = 1.9025e-12 light years
So 18 kilometers = 1.9025e-12 light years.
Quick check: 1.9025e-12 × 9.461e+12 = 18 kilometers
