What does converting millimeters to Earth's equatorial radius represent?

It represents relating tiny terrestrial linear measurements to a large-scale Earth dimension based on its equatorial radius used for geodetic and spatial referencing.

Why is the Earth's equatorial radius value standardized in this conversion?

The standard value comes from the WGS84 reference ellipsoid model, providing a consistent basis for geodetic and cartographic applications.

Are millimeter-level measurements relevant in geodetic calculations?

They are important when bridging detailed engineering scales with global Earth science models, though millimeter precision might be negligible for some geodetic tasks.
