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 Marlas
A marla is a traditional unit of land area used in Pakistan, India, and Bangladesh, equal to 30.25 square yards (approximately 25.29 m²) - effectively the same as one square rod. In Pakistan's land registry system, 20 marlas equal one kanal and 8 kanals equal one acre. Despite metrification, marla remains the dominant unit for measuring residential plots and urban land in Pakistan. Property listings in Lahore, Karachi, and Islamabad routinely quote plot sizes in marlas, making it essential knowledge for anyone dealing with South Asian real estate.
