Calculate and convert square meters, hectares, acres, and square kilometers for land and projects.
Area measures the extent of a two-dimensional surface, and it's a derived quantity — mathematically, the result of multiplying two length measurements. Precisely because of this, small length conversion errors compound when calculating area: a 1% error on the side of a square plot becomes nearly 2% error in total area, which explains why real estate documents and engineering projects demand such precision in these conversions. In Brazil, besides the square metre and the hectare (the standard unit for large rural properties, equal to 10,000 m²), historical regional units like the alqueire still circulate, with a value that varies significantly between states — the São Paulo alqueire is about half the size of the Minas Gerais or Goiás alqueire. This historical inconsistency makes converting old land deeds a real challenge for lawyers, real estate agents, and farmers. Internationally, the acre (used in the United States and UK) has a curious origin: in medieval times it represented the area a pair of oxen could plow in one day of work — a unit based on practical productivity, not abstract geometry. This converter precisely calculates conversions between square metres, hectares, acres, and the most commonly used Brazilian regional units, essential for anyone dealing with real estate transactions, agricultural planning, architectural projects, or simply trying to understand the real size of a property advertised in an unfamiliar unit.
1 hectare equals 10,000 square meters.
1 hectare is equal to about 2.47 acres.
Divide the value in square centimeters by 10,000.
An acre is the standard unit of area used in the United States and the United Kingdom.
Yes, we use the standard conversion factors of the International System.
