Why is the value so small when converting centimeters to astronomical units?

Because an astronomical unit represents an extremely large distance compared to a centimeter, the converted value becomes very small reflecting this huge scale difference.

In which fields is this conversion most commonly used?

This conversion is often used in astronomy, planetary science, astrophysics, and space mission planning to express orbital distances and positions within the Solar System.

Can this conversion be used for everyday measurements?

No, due to the large scale difference and resulting numerical precision issues, this conversion is not suitable for everyday measurement tasks.
