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 Centimeter [cm²]


A square centimeter (cm²) is a unit of area that represents a square with sides 1 centimeter long. It is used to measure small surfaces like paper, labels, or tiny objects.

1 cm² = 0.0001 m².
