Square Mile (US Survey)


The square mile (US survey) is a unit of area used in the United States for land measurement based on the US survey foot. It represents a square with sides 1 mile long, where a mile is defined using the survey foot rather than the international foot.


1 US survey mile = 5,280 US survey feet

1 square mile (US survey) ≈ 2.589998 km² (slightly different from the international square mile of 2.59 km²)


This unit is mostly used in land surveying and mapping within the US.


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.
