What does Earth's polar radius represent in this conversion?

It is the distance from Earth's center to the geographical pole along the rotation axis, serving as the semi-minor axis of a reference ellipsoid used in geodesy and satellite studies.

Why convert kilometers to Earth's polar radius?

To relate terrestrial distances to a geodetic scale, aiding in geodesy, GPS mapping, and satellite data interpretation based on Earth's dimensions.

Can this conversion be used for everyday travel distances?

No, it is primarily intended for large-scale planetary and geodetic calculations rather than routine distance measurements.
