1 square foot = 0.092903 square meters
Common square feet to square meters values
| Square feet | Square meters |
|---|---|
| 1 ft² | 0.092903 m² |
| 2 ft² | 0.185806 m² |
| 5 ft² | 0.464515 m² |
| 10 ft² | 0.92903 m² |
| 20 ft² | 1.8581 m² |
| 50 ft² | 4.6452 m² |
| 100 ft² | 9.2903 m² |
The exact factor is 1 ft2 = 0.09290304 m2, derived from the international foot of 0.3048 metres squared. It is common when a US apartment advert gives living area in square feet but a UK buyer, architect, surveyor, or flooring supplier works in square metres. The same conversion helps with carpet, vinyl, laminate, office space, storage units, and room-by-room comparison sheets.
How to convert
- Take the area in square feet from the listing, plan, or flooring estimate.
- Multiply the square-foot value by 0.09290304 to convert it into square metres.
- Remember that area squares the length conversion, so this is not the same as converting feet to metres once.
- Round the result after adding any waste allowance for flooring or after comparing room totals.
- For a mental check, divide square feet by 10.8, or use 100 ft2 as roughly 9.3 m2.
square metres = square feet * 0.09290304
One international foot is 0.3048 metres. A square foot is therefore a square measuring 0.3048 m by 0.3048 m, which gives 0.09290304 square metres. Multiplying by that area factor converts ft2 to m2.

Worked example
A 850 ft2 city flat listing is 850 multiplied by 0.09290304, giving 78.967584 m2. In a UK-style property comparison you would normally describe that as about 79.0 m2 before checking how much of the stated area is usable floor space.
Key facts
- 100 ft2 equals 9.290304 m2.
- 1,000 ft2 equals 92.90304 m2.
- US residential and commercial listings commonly quote area in ft2.
- UK and European flooring suppliers usually price carpet, timber, and vinyl by m2.
Tips
- Convert each room separately when comparing layouts, because total floor area can hide awkward shapes.
- For flooring orders, convert to m2 before adding the supplier waste percentage.
- Keep one decimal place for property browsing and more precision for purchase quantities.
Frequently asked questions
How many square metres in 1 square foot?+
One square foot is exactly 0.09290304 m2 using the international foot definition.
How do I convert a US property listing to m2?+
Multiply the listed square feet by 0.09290304. For example, 1,200 ft2 is 111.483648 m2.
Why is the factor not 0.3048?+
0.3048 converts feet to metres for length. Area is length times width, so the factor is 0.3048 squared, which is 0.09290304.
Should I include walls, cupboards, or stairs?+
That depends on the listing standard. The conversion only changes units; it does not decide what the measured area includes.
Things to watch
- Rounding every room before adding them can shift the final m2 total noticeably in large homes.
- Floor area standards vary by market, so a converted number may still not match a surveyor measurement.
