Area Unit Converter

• Converts between 19 common area units — such as square meter, square kilometer, hectare, acre, mu, and square foot — with instant, real-time results.
• Units are grouped into four systems: International (SI), Metric, Imperial, and Chinese Units, covering everyday, academic, and land-measurement needs.
• Enter a value in any single unit and every other unit updates automatically — conversion works both ways.
• When your value matches a familiar size, a handy hint appears (for example, “about the size of a basketball court”) to make the numbers easier to picture.

1. Open the tool page — no download or installation is required.
2. Type a number into any unit's input box; all other units convert instantly as you type.
3. Tap “Reset All” to clear every field and start a new calculation.

• The tool is completely free and requires no registration or login.
