Area Converter: Square Feet, Acres, Hectares & More
Convert common land, floor, and surface-area units through square metres with exact linear-unit relationships and clearly labelled results.
Why area factors are squared
Area measures a two-dimensional surface. Because one foot equals 0.3048 metre, one square foot equals 0.3048 squared, or exactly 0.09290304 square metre.
The same rule applies to square inches, yards, kilometres, and miles. Acres and hectares are separately defined land-area units.
Land and floor-area units
Hectares are common in metric land measurement and equal 10,000 square metres. Acres are common in US and UK land descriptions and equal exactly 4,046.8564224 square metres.
