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 Surveyors and civil engineers must interpret historical documents using survey-based values to ensure legal consistency with old plats, deeds, and boundary descriptions.
Rood (rood)
A rood equals 1/4 of an acre, or 10,890 square feet, and was used in medieval and early modern England for land measurement. The rood often appeared in agricultural records, taxation documents, and estate descriptions. Farmers used the rood to describe smaller plots of arable land, orchards, and grazing fields. Although obsolete today, the rood reflects the practical needs of historical agrarian societies, where manageable sub-acres allowed fine-grained recordkeeping and land division within larger estates.
