What exactly is Earth's polar radius?

Earth's polar radius is the distance from the Earth's center to the mean geographic pole along the rotation axis, representing the semi-minor axis of a reference ellipsoid such as WGS84.

Why convert Earth's polar radius to nanometers?

Converting to nanometers allows scientists to express very large geodetic lengths in terms comparable to atomic and molecular scales for precision modeling and scientific comparison.

Are there any challenges with this conversion?

Yes, since the magnitude difference is enormous, the resulting numbers are extremely large and may present numerical precision and practicality issues for everyday applications.
