Free Area Converter
Convert between square metres, square feet, acres, hectares and other area units.
Choose a value and the units; the tool converts using exact factors such as 1 hectare = 10,000 square metres and 1 foot = 0.3048 m, so 1 square foot = 0.09290304 square metres.
How to use the Area Converter
- Enter your values, choosing the units you are working in.
- Read the result and the supporting numbers shown beneath it.
- Check the result against a second method or a reference table before you rely on it.
About the Area Converter
Convert between square metres, square feet, acres, hectares and other area units.
Quick, reliable engineering arithmetic saves time on site and in the workshop. These tools show their working so you can check the result.
Getting started with the Area Converter
Using the area converter takes a minute or two. Your entries are saved in this browser, so you can come back later and carry on.
Tips for better results
Square units grow by the square of the length factor, so doubling a side length quadruples the area.
Keep units consistent from start to finish.
These tools are for estimates. Safety critical designs need a qualified engineer.
