What the Area Converter does
This tool converts between metric and imperial area units, which is useful for real estate, gardening, flooring, farming, and schoolwork. It handles square millimeters up to square miles, plus hectares and acres, so you can move between square meters and square feet, acres and hectares, or square kilometers and square miles in one step.
How to use it
- Enter the figure in the Value box.
- Pick your current unit in the From row (for example m²).
- Your value appears in every other unit instantly below, with nothing to click.
- Tap any unit (for example ft²) to copy its value to your clipboard.
Why it helps
Property listings, building plans, and land records often mix systems, so a quick converter saves mistakes when you compare a flat measured in square meters with one quoted in square feet, or land sold by the acre against the hectare. The factors used here are exact, and the calculation stays on your device because it runs entirely in your browser, with nothing sent to a server.
Frequently asked questions
- Which area units can I convert?
- It covers square millimeters, square centimeters, square meters, hectares, square kilometers, square inches, square feet, square yards, acres, and square miles. Any combination works, like square meters to square feet or acres to hectares.
- How big is an acre compared with a hectare?
- One hectare is 10,000 square meters and equals about 2.47 acres, so a hectare is larger. Enter 1 and pick hectare in the From row to see the exact figure on the acre card.
- Does anything get uploaded?
- No. The math runs in your browser, so your numbers never leave your device. No sign-up, no limits.
