About these units
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.
Square Dekameter (dam²)
A square dekameter equals 100 square meters and is used in agriculture, sports field planning, and land measurement in some metric-oriented countries. It is particularly useful for measuring the footprint of small buildings, gardens, or sport courts. Landscape architects and civil engineers may express project areas in dam² when m² values become too large and hectares too large-scale. Although not as common as the square meter or hectare, the dam² exemplifies the flexibility of the metric system for scaling area units to suit practical needs.
