What is the Earth's equatorial radius used for?

It is used to define reference ellipsoids and map projections in geodesy, calculate satellite orbits in aerospace, and convert coordinates in surveying and Earth science models.

Why use exameters for conversion?

Exameters are suited for expressing extremely large distances typical in astrophysics and cosmology, like distances between stars or galaxies.

Can this conversion be used for everyday measurements?

No, because exameters represent extremely large distances, making them impractical for normal Earth-scale measurements.
