About Circular Mils
A circular mil (cmil) is a unit used in electrical engineering to specify the cross-sectional area of round wires and cables. Equal to the area of a circle with a diameter of exactly one thou (one thousandth of an inch) - approximately 5.067 × 10⁻¹⁰ m² - it simplifies wire calculations: the cross-sectional area in cmil equals the wire diameter in mils, squared. US electrical codes (NEC/NEMA) specify conductor sizes in circular mils, and large cables are rated in thousands of circular mils (kcmil or MCM). A 12 AWG wire, common in US household wiring, has a cross-section of 6,530 cmil.
About Townships
A township (twp) is a large survey unit used in the US Public Land Survey System, defined as a square with sides of 6 statute miles, giving exactly 36 square miles or approximately 93,240,000 m². Each township is subdivided into 36 one-square-mile sections of 640 acres each. The Township and Range system is how most US land west of Ohio was divided and sold; township numbers and names still appear in legal land descriptions, county records, and geographic placenames across the American Midwest and West.
