Square Rod (US Survey)


A square rod (US survey) is a unit of area based on the US survey foot and rod, used primarily in land surveying in the United States.



  • 1 US survey rod = 16.5 US survey feet (exactly 16.5 feet)



  • 1 square rod (US survey) = 16.5 ft × 16.5 ft = 272.25 square feet ≈ 25.2929 m²



The US survey square rod is slightly different in exact length than the international measurement due to the foot definition but is essentially used the same way for land measurement.



Circular Inch


A circular inch is a unit of area used primarily in engineering and wire gauge measurements. It represents the area of a circle with a diameter of one inch.



  • Formula: Area = π × (radius)²



  • Since the radius is half an inch,

    Area = π × (0.5 in)² = π × 0.25 in² ≈ 0.7854 square inches (in²).



Circular inches are often used to specify cross-sectional areas of wires or pipes.
