What is a circular mil used for?

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

Why convert circular mil to square centimeters?

Converting to square centimeters helps integrate American Wire Gauge data into metric engineering and scientific contexts requiring SI units.

Can this converter be used for non-round conductor areas?

This converter assumes circular geometry and may not provide accurate results for conductors with non-round cross sections.
