About this calculator
Area measures the size of a two-dimensional surface. The metric system uses square meters and their multiples (square kilometers, hectares), while the imperial system uses square feet, square yards, acres and square miles. Because these systems were defined independently, converting between them requires precise factors.
This converter uses the square meter as its base unit. An acre is exactly 4046.8564224 m2, a hectare is 10,000 m2, and a square mile is 2,589,988.110336 m2. Enter any value and instantly see its equivalent in every other supported unit.
