Square Meters to Square Feet
Converting square metres to square feet is the home-size conversion people meet most often, because homes, apartments, and rooms are listed in square metres in most of the world and in square feet in the United States. One square metre equals 10.7639 square feet, so the conversion is a single multiplication. The free area converter above does it instantly, and this page shows the formula, a full table, and worked examples so you can check any answer by hand.
You need square metres to square feet when you compare a European apartment with an American one, read a floor plan, order flooring, or check whether furniture fits a room. A 100-square-metre apartment is 1,076.39 square feet, a 50-square-metre room is 538.19 square feet, and a 20-square-metre bedroom is 215.28 square feet. Once you know the factor 10.7639, every one of those is the same easy multiplication, and the examples below work through the values people look up most.
How Area Conversion Works
Area conversion is length conversion squared, because area is length times length. One acre is defined as exactly 43,560 square feet, one hectare as exactly 10,000 square metres, and one square metre as 10.7639 square feet. Since the factors are exact by definition, converting is not an estimate: 2 acres is 87,120 square feet every time. The only rounding happens in how many decimal places you display, which is why the area converter above lets you pick 2, 4, or 6 decimal places.
The units in everyday use split by purpose. Land is measured in acres and hectares, homes and rooms in square feet and square metres, and small surfaces in square inches and square centimetres. The United States lists homes in square feet and land in acres, while most of the world lists homes in square metres and land in hectares. That split is why conversions come up constantly: a house listing says 2,000 square feet, a plot is advertised as half an acre, and a European apartment is 100 square metres, and comparing them needs the same few multiplications.
Step-by-step: how to convert
- Pick the unit you are starting from. Check whether your number is in acres, square feet, square metres, hectares, square kilometres, square yards, square inches, or square miles, and select it in the From box.
- Pick the unit you want. Choose the target unit in the To box. The Swap button exchanges the two units if you need the reverse direction.
- Enter the value. Type the number, including decimals if you have them. The result updates as you type, so there is nothing to submit.
- Choose your precision. Use 2 decimal places for everyday answers, 4 for land or construction, and 6 when the result feeds another calculation.
- Read the full result. The converter shows the area in all eight units, so you can copy whichever form you need.
The Area Conversion Formulas
To convert acres to square feet, multiply acres by 43,560. So 2 acres times 43,560 equals 87,120 square feet. To convert square feet to acres, divide square feet by 43,560: 100,000 square feet divided by 43,560 equals 2.2957 acres, which rounds to 2.30 acres. To convert hectares to acres, multiply hectares by 2.47105: 5 hectares times 2.47105 equals 12.35525 acres. To convert square metres to square feet, multiply square metres by 10.7639: 100 square metres times 10.7639 equals 1,076.39 square feet.
A worked check keeps the arithmetic honest. One acre times 43,560 equals 43,560 square feet, which is the definition itself. Ten hectares times 2.47105 equals 24.7105 acres. Fifty square metres times 10.7639 equals 538.195 square feet, which rounds to 538.20 square feet. Because the factors are exact, you can verify any result by converting back: 87,120 divided by 43,560 returns exactly 2 acres.
Worked Examples
The table below converts the square-metre values people search for most often. Each row shows the multiplication so you can follow the arithmetic and confirm the pattern.
| Conversion | Calculation | Result |
|---|---|---|
| 1 sq m | 1 x 10.7639 | 10.76 sq ft |
| 10 sq m | 10 x 10.7639 | 107.64 sq ft |
| 20 sq m | 20 x 10.7639 | 215.28 sq ft |
| 50 sq m | 50 x 10.7639 | 538.19 sq ft |
| 100 sq m | 100 x 10.7639 | 1,076.39 sq ft |
Take the 100-square-metre row as the check: 100 times 10.7639 equals 1,076.39 square feet. That is a comfortable two-bedroom apartment in American terms. For everyday use, remembering that 1 square metre is about 10.76 square feet is enough: 10 square metres is about 108 square feet, 50 square metres about 538, and 100 square metres about 1,076.

Common Mistakes to Avoid
Most wrong area conversions come from a small set of slips. They are easy to make because area factors are large numbers, and a wrong factor still gives a number that looks like an area.
- Using a length factor for an area. One foot is 0.3048 metres, but one square foot is 0.092903 square metres, not 0.3048. Area factors are length factors squared, so never reuse a length factor directly.
- Multiplying when you should divide. Acres to square feet multiplies by 43,560, but square feet to acres divides by the same number. Using the wrong direction gives an answer off by a factor of about 1.9 billion.
- Confusing acres and hectares. A hectare is 2.47105 acres, so 10 hectares is 24.71 acres, not 10 acres. The two are often mixed up in land listings.
- Forgetting that a square mile is 640 acres. A square mile is a large area. A 640-acre farm is exactly one square mile, and a 160-acre quarter section is a quarter of a square mile.
- Rounding in the middle. Round only the final answer. Rounding 43,560 early is harmless, since it is exact, but rounding 2.47105 to 2.5 turns 10 hectares into 25 acres instead of the correct 24.71 acres.
- Forgetting the unit on the answer. A bare number such as 87,120 is meaningless without its unit. Always write the unit next to the result.
When You Need This Conversion
Area conversion shows up whenever land, homes, or rooms are measured in a different system from the one you think in, which is often, because real estate uses local units everywhere.
- Buying land. Plots are listed in acres in the United States and in hectares elsewhere, and converting lets you compare two listings fairly.
- Buying a home. American homes are listed in square feet while European homes are listed in square metres, and converting tells you which is really bigger.
- Flooring and painting. Materials are sold by the square foot or square metre, and converting the room size gives the right quantity to buy.
- Farming. Fields are measured in acres or hectares, seed and fertiliser are sold by the acre or hectare, and converting keeps the application rate right.
- Gardening. Garden beds, lawns, and patios are measured in square feet or square metres, and converting helps you order soil, turf, or pavers.
Tips for Accurate Results
A few habits make every area conversion reliable, whether you use the converter above or work it out by hand.
- Sanity-check with the anchors. One acre is 43,560 square feet, one hectare is 2.47105 acres, and one square metre is 10.7639 square feet. If your answer is far from those, recheck.
- Remember 43,560. That single number is the acre. Half an acre is 21,780 square feet, a quarter acre is 10,890, and two acres is 87,120.
- Keep full precision until the end. Let the converter carry the decimals and round only the number you write down or order to.
- Convert back as a check. Convert your answer back to the original unit. If you do not land on your starting number, something went wrong.
- Match precision to the job. A garden estimate needs one decimal place; a land purchase needs full precision. Extra digits on an estimate are false precision.
