What is a circular mil?

A circular mil is a unit of area used to express the cross-sectional area of round electrical conductors, based on a circle with a diameter of one mil (0.001 inch).

Where is the square pole used?

Square pole is an imperial unit primarily used in historical UK and US land measurements and property surveys.

Why convert circular mil to square pole?

Conversions can help relate precise electrical conductor areas to traditional land area units for archival or interdisciplinary studies.
