What is a circular mil used for?

A circular mil measures the cross-sectional area of round electrical conductors and is used mainly for wire sizing and ampacity calculations.

What does one section represent in land measurement?

One section equals one square mile, or 640 acres, and is commonly used in the U.S. Public Land Survey System for legal land descriptions.

Why convert from circular mil to section?

This conversion helps integrate electrical engineering measurements with land surveying data, particularly for spatial or cadastral information systems.
