About these units
Square Rod (rod²)
A square rod, also known as a perch or pole in some traditions, equals the area of a square one rod on each side (1 rod = 16.5 feet). This results in 272.25 square feet. Square rods were widely used in medieval English farming and early American surveying to measure garden plots, small fields, and building sites. Because land taxes were often assessed per rod, the unit became a practical economic tool as well. Though no longer widely used, the square rod appears in historical deeds and archival surveys, making it critical for land historians and legal property research.
Circular Inch (circ in)
A circular inch represents the area of a circle with a diameter of exactly one inch. This yields an area of approximately 0.7854 square inches. It is sometimes used in engineering, especially in the sizing of pipes, hydraulic fittings, and certain mechanical components where circular cross-sections dominate. While not as widespread as the square inch, the circular inch offers a more direct representation of the actual shape of round components, reducing the need for manual geometric conversion.
