About this tool
This free area converter moves between metric units such as square millimeters, square centimeters, square meters, hectares and square kilometers and imperial units such as square inches, square feet, square yards, acres and square miles. That makes it well suited to real-estate listings, land and farm measurements, flooring and paint estimates, gardening, architecture and geography homework — anywhere a floor plan, plot or region needs to be expressed in a different unit.
Area factors are the square of the matching length factors, which is why the numbers grow quickly: one square meter is about 10.7639 square feet, one hectare is 10,000 square meters, and one acre is 4,046.8564224 square meters. All conversions are computed locally in your browser using these exact factors, so nothing you enter is uploaded and the tool works even without an internet connection.
