Area
A hectare is 10,000 m². An international acre is 4046.8564224 m².
How it works
Area grows with the square of length. Doubling the side of a lot quadruples the area. The page only converts units that are already areas.
The Brazilian alqueire is omitted because the paulista, mineiro and northern measures are different numbers.
