A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch or 0.0254 mm). It is equal to π /4 square mils or approximately 5.067 × 10 −4 mm 2 .
Thousandth of an inch, an inch-based unit often called a thou or a mil. Circular mil, a unit of area, equal to the area of a circle with a diameter of one thousandth of an inch. Square mil, a unit of area, equal to the area of a square with sides of length of one thousandth of an inch.

The next wire size thicker than 4/0 has a cross section of 250 kcmil. A circular mil is the area of a wire one mil in diameter. One million circular mils is the area of a circle with 1,000 mil (1 inch) diameter. An older abbreviation for one thousand circular mils is MCM.
1 square mil is equal to: 1 millionth of a square inch (1 square inch is equal to 1 million square mils) 6.4516 × 10 −10 square metres; about 1.273 circular mils (1 circular mil is equal to about 0.7854 square mils). 1.273 ≈ 4 / π and 0.7854 ≈ π / 4 .
No. 7/0, the largest size, is 0.50 inches (500 mils or 12.7 mm) in diameter (250 000 circular mils in cross-sectional area), and the smallest, No. 50, is 0.001 inches (1 mil or 25.4 μm) in diameter (1 circular mil [cross-sectional area] or 0.7854 millionths of a square inch).
A circular measure was used in comparing circular cross-sections, e.g., of wires, etc. A circular unit of the ares is the area of the circle whose diameter is one linear unit. [1] For example, 1 circular mil is equivalent to 0.7854 square mil in area, 1 circular millimeter
Thickness of aluminum foil is measured in mils (1 ⁄ 1000 inch, or 0.0254 mm) in the United States. Cross-sectional area of electrical wire is measured in circular mils in the U.S. and Canada, one circular mil (cmil) being equal to 5.067 × 10 −4 mm 2 (or 7.854 × 10 −7 in 2). Since this is so small, actual wire is commonly measured in ...
