What is an astronomical unit used for?

It measures large distances within the Solar System, like planetary orbits and spacecraft trajectories.

Why convert astronomical units to micrometers?

To express enormous cosmic distances in a smaller, standardized SI unit for scientific and engineering comparisons.

Is this conversion practical for daily use?

No, due to the extremely large numbers involved, it is mainly intended for scientific or theoretical purposes.
