Circular Mil


A circular mil is a unit of area used mainly to measure the cross-sectional area of round wires and cables in electrical engineering.



  • Defined as the area of a circle with a diameter of 1 mil (1 mil = 0.001 inch).



  • Area = (diameter in mils)² circular mils.



  • 1 circular mil ≈ 7.854 × 10⁻¹⁰ square meters or 0.7854 square mils.



Circular mils simplify calculations for round wires since area scales with the square of the diameter.



Section


A section is a land measurement unit used in the United States Public Land Survey System (PLSS). It refers to a square area that is 1 mile on each side, covering:



  • 1 square mile



  • 640 acres



  • Approximately 2.59 square kilometers



Sections are the basic units within a township (which contains 36 sections) and are commonly used for legal land descriptions and property boundaries.
