What is a circular mil?
A circular mil is the area of a circle one mil — one thousandth of an inch — in diameter: about 5.067 × 10⁻¹⁰ square meters.
Electricians use it constantly because wire sizes in North America are quoted in circular mils, and the resistance of a wire follows directly from that figure.
