What is Earth's equatorial radius?

It is the straight-line distance from Earth's center to the equator along the equatorial plane, standardized at about 6,378,137 meters per WGS84.

Why convert Earth's equatorial radius to meters?

Meters provide a universally accepted linear measurement useful for engineering, mapping, and scientific applications involving Earth measurements.

Does this conversion apply universally?

This conversion is based on WGS84 ellipsoid values; variations may exist with different geodetic models.
