Square Foot (US Survey)


The square foot (US survey) is a unit of area based on the US survey foot, which is slightly longer than the international foot. It is mainly used in land surveying and mapping in the United States.



  • 1 US survey foot = 1200⁄3937 meters (approximately 0.3048006096 m)



  • 1 square foot (US survey) ≈ 0.0929034116 m²



This unit helps maintain consistency in US land measurements, especially in legal and cadastral contexts.


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.
