About Homesteads
A homestead is a land area unit of exactly 160 acres (approximately 64.75 hectares or 0.6475 km²) - one quarter of a one-square-mile section - established by the US Homestead Act of 1862. The Act promised 160 acres to settlers willing to farm the land for five years, transforming the American West: over 270 million acres (about 10% of the entire continental US) were granted to 1.6 million homesteaders. In the US Public Land Survey System, one homestead equals a quarter-section, with four homesteads forming one full section of 640 acres.
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.
