About these units
Acre (US Survey) (ac (US))
The US survey acre is based on the US survey foot, making it slightly different from the international acre. With a value of 43,560 survey-square feet, it appears extensively in historical property records and federal land surveys. Because millions of acres in the United States were mapped using PLSS, the survey acre remains necessary for interpreting legal land rights, even though modern mapping often uses metric units or the international foot. This specialized acre illustrates how subtle unit differences can survive for centuries due to legal and administrative inertia.
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.
