About these units
Square Foot (US Survey) (ft² (US))
The US survey square foot is defined using the US survey foot and differs minutely from the international square foot. While the difference is negligible in everyday contexts, in land surveying even tiny discrepancies matter because property boundaries, right-of-way extents, and engineering alignments may accumulate errors over long distances. Surveyors and civil engineers must interpret historical documents using survey-based values to ensure legal consistency with old plats, deeds, and boundary descriptions.
Square Pole (pole²)
A square pole is yet another equivalent to the square rod and square perch. The triple terminology reflects different regional dialects and occupational vocabularies within the British Isles. The persistence of three names for the same unit illustrates the decentralized nature of early measurement standards, where local custom often outweighed national regulation. Although modern metrication has replaced these units, they remain historically important when examining rural land divisions and genealogical land records.
