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.
Square Chain (ch²)
A square chain equals the area of a square one chain (~66 feet) per side, resulting in 4,356 square feet, or exactly 1/10 of an acre. This unit is closely linked to the chain, a surveyor's unit standardized by Edmund Gunter in the 17th century. Because 10 square chains make an acre, survey calculations for early colonial and American lands were extremely efficient. Square chains allowed surveyors to map and divide land rapidly using ropes or metal chains, producing a legacy seen in long, straight property lines still visible today across rural landscapes.
