No. an AU is a distance. It is the mean distance of the earth from the sun. It is approximately
1 AU = 150 million kms
Now, knowing that how much is 1.5 billion kms?

@JamesJ 0.1 AU?

Ok if
1 AU = 150 million kms
then
0.1 AU = 15 million kms
Does that sound right to you?
Also, could it possibly be the case that Saturn is closer to the sun than the earth?!

1 AU = 150 million = 150,000,000
10 AU = 1,500,000,000
100 AU = 15,000,000,000
So what's the right answer?

Wait no. The question is this: Saturn is at a distance approximately of 1.5 billion kms from the Sun.
How many AU is that?

The earth is about
150,000,000 kilometers from the sun, or
150,000,000 km
this is called 1 AU, because it's convenient.
Yes, Saturn is a distance of 10 AU from the sun.
Hence how many more times is Saturn distant from the sun than the earth?

The Earth is a distance 1 AU from the Sun
Saturn is a distance of 10 AU from the Sun
Hence Saturn is 10 times further away from the Sun than the Earth.

This works in any units of distance of course:
Earth-Sun: 150,000,000 kms
Saturn-Sun: 1,500,000,000 kms ... which is 10 times more
