Square Feet to Square Meters Converter (Sqft to Sqm)
Type an area in square feet and the converter returns square meters, written as sq m, sqm, or m2 depending on who's writing it. It runs both ways, so you can also type square meters and read off square feet. The conversion factor is fixed: one square foot is 0.092903 square meters. Below that you'll find the formula, a conversion table from 1 to 1 million square feet, and the formulas to do it in Excel or Google Sheets.
The conversion factor and formula
To convert square feet to square meters, multiply:
square meters = square feet × 0.092903
The factor isn't an approximation that somebody measured. It falls straight out of the definition of the foot. NIST lists the international foot as exactly 0.3048 meters, and the square foot as exactly 0.09290304 square meters. Area is length squared, so:
0.3048 × 0.3048 = 0.09290304 square meters per square foot
Round that to 0.092903 for everyday use, or keep all eight decimals when the numbers get large. Going the other way, one square meter is 10.7639 square feet, and the square meters to square feet converter covers that direction in full, with apartment size comparisons and hectares. For every other area unit at once, use the area converter.
Quick mental check: divide square feet by 10, then take away about 7 percent. 1,500 sq ft becomes 150, minus 10.5, which is 139.5 m2 against an exact 139.35. Close enough to sanity-check a listing.
Worked example 1: a room
A bedroom that measures 10 feet by 10 feet is 100 square feet. Convert it:
100 sq ft × 0.092903 = 9.29 m2
So a 10 by 10 room is about 9.3 square meters. It's a handy anchor to memorize, because a lot of North American rooms land near 100 sq ft and you can scale the metric size from there.
Worked example 2: a house
A 2,000 square foot US house, converted for a buyer or a relocation form that asks for square meters:
2,000 sq ft × 0.092903 = 185.81 m2
That's about 186 square meters. In most of Europe and Asia a home that size is a large family house, even though it's close to typical for new US construction. The square footage chart lists room and building sizes in both units if you'd rather look it up than multiply.

Large areas: up to a million square feet
Commercial real estate is often quoted in hundreds of thousands or millions of square feet: distribution warehouses, office towers, shopping centers, and campus totals. At that scale it helps to see hectares and acres alongside square meters.
| Square feet | Square meters | Hectares | Acres |
|---|---|---|---|
| 10,000 sq ft | 929 m2 | 0.09 ha | 0.23 acres |
| 25,000 sq ft | 2,323 m2 | 0.23 ha | 0.57 acres |
| 50,000 sq ft | 4,645 m2 | 0.46 ha | 1.15 acres |
| 100,000 sq ft | 9,290 m2 | 0.93 ha | 2.30 acres |
| 250,000 sq ft | 23,226 m2 | 2.32 ha | 5.74 acres |
| 500,000 sq ft | 46,452 m2 | 4.65 ha | 11.48 acres |
| 1,000,000 sq ft | 92,903 m2 | 9.29 ha | 22.96 acres |
A million square feet is 92,903 square meters, a little over 9 hectares. That's the scale of a large fulfilment center. Floor area figures that big are usually gross building area or gross leasable area rather than living area, and commercial square footage explains how those differ. Keep the full 0.09290304 factor at this size: rounding to 0.0929 drops about 3 square meters per million square feet, which is trivial, but rounding to 0.093 adds nearly 100.
Feet to meters conversion chart (for measuring dimensions)
If you measured a room in feet and want its metric dimensions rather than just its area, convert each side as a length first. If you already have the dimensions in meters or centimeters, the square meter calculator multiplies them for you. The length factor is different: one foot is 0.3048 meters.
| Feet | Meters |
|---|---|
| 1 ft | 0.3048 m |
| 5 ft | 1.52 m |
| 8 ft | 2.44 m |
| 10 ft | 3.05 m |
| 12 ft | 3.66 m |
| 15 ft | 4.57 m |
| 20 ft | 6.10 m |
| 25 ft | 7.62 m |
| 30 ft | 9.14 m |
| 40 ft | 12.19 m |
| 50 ft | 15.24 m |
| 100 ft | 30.48 m |
A 12 by 15 foot room is 3.66 by 4.57 meters, and 3.66 x 4.57 = 16.7 m2. Converting the area directly, 180 sq ft x 0.092903, gives the same 16.7 m2. Either route works, as long as lengths use 0.3048 and areas use 0.092903.
One thing that can't be done is converting square feet to meters. Square feet measure area and meters measure length, so there's no single answer. What you can do is work out the side of a square with that area: 1,000 sq ft is a square about 31.6 feet on a side, which is 9.64 meters.
Square feet to square meters in Excel and Google Sheets
For a column of values, a spreadsheet does it in one formula. With square feet in cell A2:
Plain multiplication, works everywhere:
=A2*0.09290304
The CONVERT function. Excel's CONVERT function takes the value and two unit codes, and Microsoft's documentation lists square feet as "ft2" or "ft^2" and square meters as "m2" or "m^2". Google Sheets has the same function, and its area units include "ft^2" and "m^2". The caret form works in both, so it's the safer one to use:
=CONVERT(A2,"ft^2","m^2")
To round to two decimal places, wrap it: =ROUND(CONVERT(A2,"ft^2","m^2"),2). Fill the formula down the column and every row converts. To go the other way, swap the two unit codes.
The CONVERT codes are case sensitive, and a typo returns an #N/A error rather than a wrong number, which is a useful safety net. The multiplication version will quietly give a wrong answer if you type the factor wrong, so it's worth checking one row against the table above.
Common room sizes in both units
Whole-house numbers are easy to convert but hard to picture. Room sizes land closer to home.
| Space | Square feet | Square meters |
|---|---|---|
| Small bedroom (10 by 10) | 100 sq ft | 9.29 m2 |
| Standard bedroom (12 by 12) | 144 sq ft | 13.38 m2 |
| Master bedroom (14 by 16) | 224 sq ft | 20.81 m2 |
| Kitchen (12 by 14) | 168 sq ft | 15.61 m2 |
| Living room (16 by 20) | 320 sq ft | 29.73 m2 |
| Two-car garage (20 by 20) | 400 sq ft | 37.16 m2 |
| Studio apartment | 500 sq ft | 46.45 m2 |
Most single rooms fall between 9 and 30 square meters, so if a metric floor plan lists a bedroom as 11 m2 you already know it's a touch bigger than a standard 10 by 10.
Why this conversion matters internationally
Most of the world measures floor area in square meters. The United States, and to a lesser extent the UK and Canada in everyday real estate talk, still lean on square feet. So the moment you look at property abroad, fill in a relocation or visa form, read an architectural drawing from a metric firm, or compare a US listing against one in Europe or Asia, you're bridging the two systems.
A few practical spots where it bites. Industrial leases are often quoted per square meter in one country and per square foot in another, and the per unit rate looks wildly different until you convert. Flooring and tile from overseas manufacturers may list coverage in square meters per box. When you're comparing land rather than floor area, the square footage to acres converter covers the other unit that trips people up, and the guide to calculating square footage shows how to get an accurate number before you convert it.
How listing sizes are measured differently in the US and metric countries
Converting the number is the easy part. The trap is that "floor area" doesn't mean the same thing everywhere, and the raw conversion hides it.
In the US, residential square footage generally follows the ANSI Z765 standard: finished, above grade living space, measured to the outside faces of the exterior walls, so the thickness of the walls is counted. Fannie Mae requires the standard for appraisals, which means a US figure is usually gross living area, walls included. How square footage is measured covers who produces the number and why it varies.
Many metric countries advertise a net or usable figure instead. In France, the loi Carrez requires the private floor area of most apartments to be stated, and it leaves out walls, stairs, and any space with a ceiling under 1.80 meters. In India, listings distinguish carpet area (the floor you can walk on), built up area (carpet plus walls), and super built up area (which loads in a share of hallways and common space), and the same flat can look 20 to 30 percent bigger under the super built up figure.
So a US home of 1,000 square feet converts to 92.9 m2, but a Paris apartment advertised at 93 m2 under Carrez rules is probably somewhat larger in gross terms. Convert the units first, then ask which standard produced each one.
Common mistakes
Using 10.764 instead of 0.0929. They're inverses, so swapping them throws the answer off by a factor of more than 100. Square meters are bigger than square feet, so the same space is always a smaller number in square meters. If your metric figure came out larger, you multiplied by the wrong factor.
Converting area with the length factor. 0.3048 is for feet to meters as a length. Using it on square feet gives an answer more than three times too big. Areas need 0.092903.
Asking for "square feet to meters." Area and length are different kinds of measurement and don't convert into each other. You want square meters.
Rounding too early on big numbers. On a house it barely matters. On a commercial figure in the hundreds of thousands, use 0.09290304 and round at the end.
FAQ
How do I convert square feet to square meters?
Multiply the square footage by 0.092903. For example, 500 square feet times 0.092903 equals about 46.45 square meters. The factor comes from squaring the foot to meter length conversion, 0.3048 times 0.3048.
What is the conversion factor from square feet to square meters?
0.09290304, exactly. One foot is defined as 0.3048 meters, and 0.3048 squared is 0.09290304. Most people round it to 0.092903 or 0.0929. The reverse factor, square meters to square feet, is 10.7639.
What is 100 sq ft in m2?
9.29 square meters. That's a 10 by 10 foot room.
How many square meters is 1,000 square feet?
92.9 square meters. By international standards that's a roomy two bedroom apartment. Round it to 93 m2 in conversation.
What is 1,200 sq ft in square meters?
111.48 square meters. 1,500 square feet is 139.35 m2, and 3,000 square feet is 278.71 m2.
What is 2,000 square feet in square meters?
185.81 square meters, or about 186 m2. That's a typical newer US single-family home and a large house by European standards.
How many square meters is 1 million square feet?
92,903 square meters, which is about 9.29 hectares or 23 acres. Figures that size are usually commercial gross building area, such as a large warehouse or office campus.
How do I convert square feet to square meters in Excel?
Use =CONVERT(A2,"ft^2","m^2") with the square footage in A2, or multiply directly with =A2*0.09290304. The CONVERT version with the caret unit codes also works in Google Sheets.
Is a square meter bigger than a square foot?
Yes, by a lot. One square meter is almost 11 square feet, so any area is always a smaller number in square meters than in square feet. If the metric figure comes out larger, the conversion was done backward.
Is a square meter apartment size net or gross?
It depends on the country. France quotes a net usable figure under the loi Carrez that excludes walls and low-ceiling areas, while US square footage under ANSI Z765 is a gross figure measured to the outside of the exterior walls. The unit conversion is identical either way, but the area being measured is not.
