What 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 and represents the semi-minor axis of a reference ellipsoid such as WGS84.

Why convert Earth's polar radius to dekameters?

Converting to dekameters allows expressing very large geodetic distances in units related to tens of meters, making them easier to interpret for mapping, surveying, and meteorological applications.

Can I use this conversion for precise measurement tasks?

This conversion is mainly for expressing large Earth-scale distances and may not provide sufficient precision for tasks requiring meter or sub-meter accuracy.

Limitations

Earth's polar radius is a fixed constant and does not vary, unlike typical length units
Dekameters suit medium-scale distance representation but lack precision for detailed geodetic measurements
Conversion expresses large Earth distances in a scaled unit and is not intended for direct practical interchange
The precision of dekameters may not meet sub-meter geodesy or surveying requirements
