Why is Earth's distance from the Sun expressed as an astronomical unit (AU)?

It serves as a standard length scale for distances within the solar system, facilitating consistent measurement and comparison.

What does the Bohr radius represent in physics?

It is the atomic unit of length indicating the most probable distance between the hydrogen nucleus and its electron in the ground state.

Can this converter be used for everyday length conversions?

No, Bohr radius units are specific to quantum physics and not practical for general length measurements.
