About the Area Converter
Area conversions come up in real estate, agriculture, mapping and construction. Square metres and square feet are the most common for indoor spaces, while acres and hectares are used for land. This converter covers all standard area units with a live reference table.
Common uses: comparing property sizes between countries (m² vs ft²), understanding agricultural land measurements (acres vs hectares), converting map scales, and construction planning.
The most common conversion by far is square feet to square metres — used whenever comparing US and UK property listings. A UK flat listed at 65 m² and a US apartment listed at 700 sq ft are roughly the same size (65 m² ≈ 700 sq ft). The other high-use pair is acres vs hectares: 1 hectare equals 2.47 acres, which comes up constantly in agriculture, forestry and land planning.
The reference table shows all area units simultaneously so you can cross-reference values without switching back and forth. Enter any value and every unit updates at once — square millimetres, square centimetres, square metres, hectares, square kilometres, square inches, square feet, square yards, and acres.
