Square Meter [m²]


A square meter (m²) is the SI unit of area. It represents the area of a square with sides that are 1 meter long. Square meters are commonly used to measure spaces like rooms, land, and buildings. For example, a room that is 5 meters long and 4 meters wide has an area of 20 m² (5 × 4 = 20).


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.
