Arealenheter

Arealenheter are units used to express the size of a two-dimensional area in land and property contexts. In Norwegian and Swedish usage they describe measurements of land, plots, buildings and other surfaces in maps, cadastre records and real estate descriptions. The most common contemporary arealenhet is the square meter (m^2), the SI unit for area. For larger areas, square kilometers (km^2) and hectares (ha) are widely used. A traditional Scandinavian unit is the are, equal to 100 m^2; and 1 hectare equals 100 ares.

In practice, the choice of arealenhet depends on context. Real estate listings often present areas in m^2 or ha; urban planning and construction use square meters for plot sizes, while regional land areas may be described in km^2 or ha. In geographic information systems and cadastral records, area values are stored in square meters internally, with conversions applied for display.

The concept of arealenhet highlights that area is a measurable property rather than a fixed region, and the term is part of standard vocabulary in Nordic languages for land measurement. See also area, cadastral survey, land use planning, hectare.
