📐 Sq Ft to Sq M Converter
Convert square feet to square metres and back. The exact factor, a table of the values people look up most, and what each unit is actually used for.
Converting square feet to square metres
One square foot is 0.09290304 square metres, and one square metre is 10.76391042 square feet.
square metres = square feet × 0.09290304
Getting the precision right
One square foot is exactly 0.09290304 m², which is 0.3048 squared. The trap is that area scales with the square of length, so a room twice as long on each side has four times the area — people routinely convert the sides and then forget to square the factor.
Where each unit is used
Property is advertised in square feet in the United States, the United Kingdom, India and Hong Kong, and in square metres across most of Europe and Latin America. Anyone comparing property listings across those markets needs this conversion before the prices mean anything.

1,000 sq ft is 92.9 m², a typical two-bedroom flat. A 12 by 12 ft room is 144 sq ft or 13.4 m². A UK new-build one-bedroom minimum of 50 m² is 538 sq ft.
Where the two units came from
Property markets are unusually resistant to changing their area unit, because every historical listing and every comparison a buyer makes is anchored to it. That is why square feet persist in the United States, the United Kingdom, India and Hong Kong while the surrounding economies went metric. Hong Kong is the extreme case: flats are advertised in square feet even though the territory has been officially metric since the 1970s.
Round the result to the precision your own work needs. These converters carry the full factor, which is useful for checking but rarely what you want to write down.
If the number here raised another question, it is probably one of these: the acres to hectares or the days to hours.
Frequently Asked Questions (FAQs)
How many square metres are in a square foot?
0.09290304, which is 0.3048 squared. Going the other way, one square metre is 10.764 square feet.
Why is the factor not 3.28?
Because 3.28 converts length, not area. Area needs the factor squared, so 3.280839895 becomes 10.764 square feet per square metre. Using the length factor by mistake understates the area by a factor of more than three.
How big is 1,000 square feet?
92.9 square metres, which in most markets is a comfortable two-bedroom flat. For a sense of scale, it is roughly a 30 by 33 foot rectangle, or 9 by 10 metres.
