About these units
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.
Square Rod (US Survey) (rod² (US))
The US survey square rod is defined using the survey foot and differs negligibly from the international square rod. This distinction matters in legal contexts, especially when interpreting older property descriptions dating back to the 19th-century PLSS-era surveys. The unit persists primarily in legal documents and rural land records, ensuring that historical boundaries remain consistent even as measurement standards evolve.
