How do you convert scientific notation to AU?

One astronomical unit (AU) is 150 million km = 1.5 × 108 km. Dividing the first number by the second, we get 3.27 × 10(9 – 8) = 3.27 × 101 AU.

What is a light year vs astronomical unit?

One light year is almost six trillion miles. And an astronomical unit is the average distance between the earth and the sun. So the distance to the sun is by definition one AU. A parsec is the distance at which one astronomical unit subtends an angle of one second of arc.
