What does Earth's polar radius measure?

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

Why convert Earth's polar radius to picometers?

To express large terrestrial distances in extremely small atomic-scale units, enabling scientific computations that cross vastly different length scales.

Is this conversion commonly used in everyday applications?

No, it's mainly theoretical and used in scientific research due to the extreme difference in scale between these units.
