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 Hectometer (hm²)
A square hectometer, equal to 10,000 square meters, is equivalent to a hectare, making it a significant land unit in agriculture, forestry, and environmental planning. While the term "hectare" is far more common, hm² is technically valid within the SI framework and occasionally used in scientific or engineering reports where strict SI formatting is preferred. The unit's scale makes it ideal for measuring fields, park areas, forest plots, and moderate land parcels. Its equivalence to the hectare ensures its place in practical land measurement.
