Full precision:1.203e-7 AU
Feet + Inches:2325004' 7.8"
Step-by-Step Solution
To convert 18 kilometers to astronomical units, we divide by 149600000 because one astronomical unit equals exactly 149600000 kilometers.
1 astronomical unit = 149600000 kilometers
Since there are 149600000 kilometers in every astronomical unit, we divide our value by this factor:
18 ÷ 149600000 = 1.2032e-7 astronomical units
So 18 kilometers = 1.2032e-7 astronomical units.
Quick check: 1.2032e-7 × 149600000 = 18 kilometers
