Area Converter

This is a cleanly designed, intuitive area unit conversion tool that allows real-time bidirectional conversions between various area units. Users can freely input values in either the left or right field, and the system will automatically calculate and display the corresponding result in sync, with no need to click any buttons for conversion.

The tool supports a wide range of common area units, including metric units such as square millimeters (mm²), square centimeters (cm²), square meters (m²), square kilometers (km²), ares (a), and hectares (ha); as well as imperial units like square inches (in²), square feet (ft²), square yards (yd²), and acres. It also specifically supports the unit “ping,” commonly used in Taiwan and Japan, making it especially useful for local applications in land measurement, interior design, and construction calculations.
