square meters to square feet calculator
A square meters to square feet calculator multiplies by 10.7639: 100 m² is 1,076.4 sq ft, or 119.60 square yards. Includes a reference table and the formula.
Square meters to square feet calculator
A square meters to square feet calculator multiplies an area in square meters by 10.7639. A 100 m² area equals 1,076.4 square feet, and the same 100 m² is 119.60 square yards. Enter the number of square meters and both results appear.
The formula in plain words
Square feet = square meters × 10.7639.
Square yards = square meters × 1.19599.
The factor comes from length. One meter is 3.28084 feet. Area is length times width, so you multiply that by itself: 3.28084 × 3.28084 = 10.7639.
Worked examples
The default, 100 m²:
- Square feet: 100 × 10.7639 = 1,076.4
- Square yards: 100 × 1.19599 = 119.60
A living room of 25 m²:
- Square feet: 25 × 10.7639 = 269.1
- Square yards: 25 × 1.19599 = 29.90
A bedroom measured 3 m by 4 m:
- Area: 3 × 4 = 12 m²
- Square feet: 12 × 10.7639 = 129.2
- Check by feet: 3 m is 9.84 ft and 4 m is 13.12 ft, and 9.84 × 13.12 = 129.1, which matches within rounding
Conversion table
| Square meters | Square feet | Square yards |
|---|---|---|
| 1 | 10.8 | 1.20 |
| 5 | 53.8 | 5.98 |
| 10 | 107.6 | 11.96 |
| 20 | 215.3 | 23.92 |

| 150 | 1,614.6 | 179.40 |
| 200 | 2,152.8 | 239.20 |
For any other number, multiply by 10.7639. For a rough mental estimate, multiply by 10 and add about 8 percent.
Where the conversion comes up
- A rental listing gives 65 m², and you want a feel for it in square feet: 65 × 10.7639 = 699.7 sq ft.
- Flooring sold in a European catalog gives coverage per pack in square meters, and you need to compare with a US box.
- A paint or tile calculator expects square feet, but your plan is metric.
- A land parcel listed in square meters needs a conversion to acres. Convert to square feet first, then use the square feet to acres calculator.
Going the other way
To go from square feet to square meters, divide by 10.7639. That is the same as multiplying by 0.0929. The square feet to square meters calculator does this directly. For square yards to square feet, the square yards to square feet calculator multiplies by 9.
How to measure the area first
If you do not have the area yet, measure in meters.
- Rectangle: length × width.
- Triangle: base × height ÷ 2.
- Circle: 3.1416 × radius × radius.
- L-shaped room: split into two rectangles and add.
The square footage calculator handles shapes if you would rather work in feet.
A quick sanity check
Before you trust any conversion, check that the answer is about ten times the metric number. A room of 12 m² should land near 120 sq ft, and the exact answer of 129.2 is a little above that, as it should be. If your answer is close to 12 or to 1,200 instead, the factor was applied the wrong way or twice.
A second check is to convert the sides. If a room is 3 m by 4 m, work out each side in feet, then multiply. The two methods should agree to within a fraction of a square foot.
Rounding
The calculator shows square feet to one decimal place and square yards to two. If you are ordering material, round up to a whole unit after adding waste. For example, 129.2 sq ft of tile plus 10 percent waste is 142.1 sq ft, so order at least 143 sq ft of tile.
Common mistakes
- Using the linear factor of 3.28084 for area. That is for lengths.
- Confusing m² with m³. Cubic meters measure volume.
- Dividing instead of multiplying. Feet are smaller than meters, so the number of square feet is always larger.
- Rounding the factor to 10.7 or 10, which can cost you a few square feet on a large floor.
- Mixing metric and US dimensions in the same calculation without converting first.
Frequently asked questions
How many square feet are in a square meter?
One square meter is 10.7639 square feet. A meter is 3.28084 feet, and squaring that gives the area factor. So a 12 m² room is 12 × 10.7639 = 129.2 sq ft.
Why would I convert square meters to square feet?
Floor plans, apartment listings and tile or flooring products outside the US usually give areas in square meters, while US suppliers sell by the square foot. Converting lets you compare sizes and order material in the units your store uses.
Is the conversion exact or approximate?
The foot is defined as exactly 0.3048 m, so the true factor is 10.76391041... The calculator uses 10.7639, which differs by less than one part in 100,000. For any building job, that difference is far below your measuring error.
How do I convert square meters to square yards?
Multiply by 1.19599. A 100 m² area is 119.60 square yards. The calculator shows this as a second result. You can also convert to square feet first and divide by 9.
How do I go from square feet back to square meters?
Divide by 10.7639, or multiply by 0.0929. A 1,000 sq ft floor is about 92.9 m². Our square feet to square meters calculator does that direction.
