What is a circular mil used for?

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

Why would I need to convert circular mil to square perch?

Conversion helps interpret electrical wire areas alongside historical land measurement units in archival research or legal conveyancing.

Is the square perch still commonly used today?

No, the square perch is an obsolete unit mostly relevant for historical land measurement and surveying.
