When Each Unit is Used
Hectares (ha)
EU countries, Commonwealth (except UK agriculture), scientific and planning contexts. Used in land registration in most of the world. One hectare is exactly 100m x 100m = 10,000 m2.
Acres
UK agriculture (traditional), US real estate and land measurement. An acre is defined as 43,560 ft2 or 4,840 sq yards. The US public land survey system divides land into square miles (sections), each of 640 acres.
Square kilometres (km2)
National statistics, administrative area reporting, geography. 1 km2 = 100 hectares = 247 acres.
Square miles
US federal contexts, UK area reporting, geography. 1 sq mile = 640 acres = 258.999 ha.
Square metres (m2)
Individual property sizes, floor areas, small plots. Inappropriate for land parcels over ~2 hectares due to unwieldy numbers.
