How to convert square feet to square meters
Multiply the area in square feet by 0.09290304, or divide it by 10.7639104. That figure is not an approximation to remember: it is exactly 0.3048 × 0.3048, because a foot is exactly 0.3048 m.
Worked example: an apartment is listed as 1,200 sq ft. 1,200 × 0.09290304 = 111.4836 m². A 12 ft by 15 ft room is 180 sq ft, which is 16.72 m². Check by converting the sides: 12 ft = 3.6576 m and 15 ft = 4.572 m, and 3.6576 × 4.572 = 16.7225.
A common slip is multiplying by 0.3048 instead of 0.0929. That gives an answer about 3.3 times too big. The shortest check: a square meter is a bit more than 10 square feet, so the number of square meters should be about a tenth of the number of square feet.

Property listings in the US give floor area in square feet, while listings in much of the rest of the world use square meters. Listings can also measure floor area differently (inside the walls, or including them), so converting the unit does not make two listings directly comparable.
Flooring, paint and tiles
- Flooring and tiles are sold per square foot in the US and per square meter in many other places. One square meter takes 10.76 ft² of material, and you will want extra for cuts and waste.
- A box of tiles that covers 15 ft² covers 1.394 m². A 20 m² floor needs 215.3 ft².
- Paint coverage is often printed as square feet per gallon in the US and square meters per liter elsewhere. Work out the wall area first, then convert that one figure.
- Heating, cooling and rent guides often quote a cost or a rating per square foot or per square meter. Divide a price per ft² by 0.0929 to get the price per m²: a rent of $2 per ft² is about $21.53 per m².
