What is Earth's polar radius?

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

What is a barleycorn used for?

The barleycorn is a historic unit of length approximately one third of an inch, traditionally used in British shoe sizing and interpreting historical measurement documents.

Why convert Earth's polar radius to barleycorn?

Converting to barleycorn helps express very large geodetic distances in a traditional British unit, which can be useful for historical research or understanding older technical records.
