About these units
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.
Square Mile (US Survey) (mi² (US))
The US survey square mile is extremely close to the international square mile but is defined using the US survey foot, a slightly different value than the international foot historically used in land surveying. This unit appears in American land deeds, cadastral maps, and federal land management documents. The Public Land Survey System (PLSS), which divided much of the western United States into townships and sections, relied heavily on survey-based square miles. Although the modern US has transitioned to the international foot (as of 2023), historical land descriptions remain legally tied to the survey-based definition, ensuring its continued relevance.
