Step-by-Step Solution

To convert 3 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:

3 ÷ 149600000 = 2.0053e-8 astronomical units

So 3 kilometers = 2.0053e-8 astronomical units.

✓Quick check: 2.0053e-8 × 149600000 = 3 kilometers
