About these tools

These tools convert an area from one unit to another. They cover the small units used for rooms and floor plans - square feet, square metres, square inches - and the large ones used for land, such as acres, hectares and square kilometres.

Area conversion trips people up more often than length, because the ratio between two area units is the square of the ratio between the matching length units. These pages do that step for you.

How to choose

Pick the pair that matches your figures. Property listings and land records usually state their unit; if a figure looks implausible after converting, check whether the source was in area units or length units.

Frequently asked questions

Why is converting area not the same as converting length?

Because area is two-dimensional. A metre is about 3.28 feet, but a square metre is about 10.76 square feet - the ratio is squared. Doing it in one step, as these tools do, avoids that mistake.

How big is an acre in square feet?

An acre is 43,560 square feet, or about 4,047 square metres. There is a dedicated converter here for acres to other area units.

Can I convert land measurements from property documents?

Yes, as long as you know which unit the document uses. These tools convert between the units; they do not interpret a document for you.
