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.



Square Rod


A square rod (also called a perch or pole) is a unit of area used in land measurement. It is the area of a square with each side one rod long.



  • 1 rod = 16.5 feet (5.029 meters)



  • 1 square rod = 16.5 ft × 16.5 ft = 272.25 square feet ≈ 25.29 square meters



  • 160 square rods = 1 acre



Square rods were historically used in surveying and property descriptions.
