How to Convert Square Feet to Square Meters
Convert between sq ft, sq m, acres, hectares, and more. With real estate context.
Why convert square feet to square meters?
Area conversion is one of the most common tasks in real estate, construction, interior design, and land management. The square foot (sq ft) dominates the US, UK (for property listings), Canada, India, and a few other markets. The square meter (sq m or m²) is the SI standard used by the rest of the world for nearly every purpose.
You will hit this conversion when:
- Buying or renting property: A US listing says 1,500 sq ft. A European equivalent says 140 m². Which is bigger? (This guide will tell you.)
- Building or renovating: Tile, flooring, paint, and wallpaper are sold by coverage area. Mixing units silently produces 10–20% off estimates.
- Land and farming: Acres and hectares are the common large-area units. A farmer switching between them needs precise math.
- Architecture and CAD: Most international CAD software uses m² as the base unit.
The good news: the formulas are short, exact, and easy to remember.
The exact conversion formulas
Square feet to square meters
``` 1 sq ft = 0.09290304 sq m (exact, by definition) 1 sq m = 10.7639104 sq ft (exact) ```
Why the exact number: The international foot is defined as exactly 0.3048 m (since the 1959 international yard and pound agreement). Squaring that gives 0.09290304 m² for one square foot — exact, not an approximation.
Worked examples:
- 1,000 sq ft → m²: 1,000 × 0.09290304 = 92.90 m²
- 100 m² → sq ft: 100 × 10.7639104 = 1,076.39 sq ft
- 1,500 sq ft → m²: 1,500 × 0.09290304 = 139.35 m² (a typical 3-bedroom apartment in either unit)
Acres and hectares
The two large-area units you will encounter:
``` 1 acre = 4,046.8564224 sq m (exact) 1 acre = 0.40468564224 hectare 1 hectare = 10,000 sq m (exact) 1 hectare = 2.4710538147 acres 1 sq km = 100 hectares (exact) ```
A useful mental anchor: 1 hectare ≈ 2.47 acres, and 1 acre ≈ 0.405 hectare. A football field (without the end zones) is about 1 acre; a full soccer pitch is about 0.7 hectare.
Other area units worth knowing
- Square yard (sq yd): 1 sq yd = 9 sq ft = 0.83612736 m². Used in UK/US for carpet and fabric.
- Square inch: 1 sq in = 6.4516 cm² (exact). Common for screen sizes (TVs, monitors, phones).
- Ares: 1 are = 100 m². Old metric, still seen in European property listings.
- Square mile: 1 sq mi ≈ 2.59 km². Used for cities, counties, and large land parcels in the US.

Method 1: Use UtilBoxx's Area Converter (Recommended)
The fastest, most private, and most precise way to convert area in your browser is the UtilBoxx Area Converter. It supports square meters, square feet, square kilometers, acres, hectares, square miles, square yards, and more, with bidirectional instant conversion. Everything runs in your browser — no server, no upload, no logs.
How to use it:
- Go to utilboxx.com/en/tools/unit/area
- Type a value in any field (m², ft², acre, hectare, etc.)
- All other fields update instantly
- Copy the result
Why we recommend this method:
- 100% free, no signup, no email, no ads
- Privacy-first: nothing leaves your browser
- Covers all common area units: m², ft², km², acres, hectares, and more
- Exact precision — uses the precise 0.09290304 factor
- Works on any device with a browser
If you compare property listings, plan renovations, or work in real estate, this tool will pay for itself the first time you use it.
Method 2: Google Search
For a one-off conversion, Google is the fastest path. Type `1500 sq ft to m2` or `1000 square meters in square feet` into the search box. Google replies with a built-in converter card at the top of the results, including the exact conversion.
Pros: zero friction, no click required, works on any device with a browser.
Cons: requires an internet connection, only good for one value at a time, and Google logs every conversion. For privacy-sensitive values (real estate decisions, confidential property data), prefer an offline method. Google also handles acres and hectares well, but unusual units like ares or square rods may need an additional click.
Method 3: Python (or any language)
A few lines of Python cover every area conversion. The same factor of 0.09290304 is exact, so you can use it without worrying about floating-point drift.
```python SQM_PER_SQFT = 0.09290304
def sqft_to_sqm(sqft): return sqft * SQM_PER_SQFT def sqm_to_sqft(sqm): return sqm / SQM_PER_SQFT
print(sqft_to_sqm(1500)) # 139.35456 print(sqm_to_sqft(100)) # 1076.3910416709721
# Acres and hectares SQFT_PER_ACRE = 43560 SQM_PER_HECTARE = 10000 SQM_PER_ACRE = 4046.8564224
def acres_to_hectares(ac): return ac SQM_PER_ACRE / SQM_PER_HECTARE def hectares_to_acres(ha): return ha SQM_PER_HECTARE / SQM_PER_ACRE
print(acres_to_hectares(2.5)) # 1.01171... print(hectares_to_acres(1)) # 2.47105... ```
JavaScript, with the same idea:
```js const SQM_PER_SQFT = 0.09290304; const sqftToSqm = sqft => sqft * SQM_PER_SQFT; const sqmToSqft = sqm => sqm / SQM_PER_SQFT; console.log(sqftToSqm(1500).toFixed(2)); // 139.35 ```
For batch conversion of property data (a CSV with sq ft prices per region, for instance), a 3-line pandas script processes thousands of rows in milliseconds.
Method 4: CLI with units (Linux/macOS)
The GNU `units` utility handles area conversion on the command line. Install on macOS with Homebrew (`brew install units`).
```bash # Convert 1500 sq ft to m² units "1500 sqft" "m2" # 139.35456
# Convert 1 acre to hectares units "1 acre" "hectare" # 0.40468564
# Convert 1 hectare to acres units "1 hectare" "acre" # 2.4710538 ```
`units` understands many synonyms (`sq ft`, `square feet`, `ft²`, `m²`, `sq m`, etc.) and handles compound expressions. It is the fastest path for one-off area math in a shell session, and ideal for shell scripts that need to embed conversions in pipelines.
Common questions
Is 1,500 sq ft a big apartment?
It depends on the market. In Manhattan, 1,500 sq ft (~139 m²) is a very large 3-bedroom apartment. In suburban Texas, 1,500 sq ft is a modest starter home. In Mumbai or Tokyo, 1,500 sq ft would be a luxury apartment. The number alone is meaningless without the city context. The size of a "comfortable" home varies by 3-4x between markets.
How many sq ft is a "1 BHK" in India?
"BHK" stands for Bedroom, Hall, Kitchen. A 1 BHK in India typically ranges from 400 to 700 sq ft (37–65 m²). A 2 BHK is 700–1,200 sq ft. A 3 BHK is 1,200–2,000 sq ft. These vary widely by city — Mumbai and Delhi are tighter, Bangalore and Hyderabad more spacious.
What is a "guntha" or "cent" in Indian real estate?
Older Indian property units: 1 guntha = 1,089 sq ft (used in Maharashtra, Karnataka). 1 cent = 435.6 sq ft (used in South India, 1 cent = 1/100 acre). Modern Indian real estate has largely standardized to sq ft for apartments and acres for land, but rural property transactions still use guntha and cent.
Why do some US homes list sq ft and others list acres?
Different markets and different property types. Apartments, condos, and houses are listed in square feet because buyers care about interior floor area. Land, farms, and rural properties are listed in acres because buyers care about total land area. A 1,500 sq ft house on 0.25 acres is a typical suburban lot. A 1,500 sq ft house on 5 acres is a small farm.
Is a hectare bigger than an acre?
Yes. 1 hectare = 2.47 acres. Both are roughly the size of a sports field, but a hectare is closer to 2.5 American football fields, while an acre is about 1 football field. Hectares are the standard unit in the metric system; acres persist in the US, UK, and a few other markets for historical reasons.
How precise is 1 sq ft = 0.09290304 sq m?
Exact. Since 1959, the international foot is defined as exactly 0.3048 m. Squaring that gives 0.09290304 m² per square foot — exact, not an approximation. Any tool or formula that uses this number is using the precise international standard. Older US survey foot (1 ft = 1200/3937 m) gives a slightly different factor of about 0.09290304 m² as well, but the difference is in the 9th decimal.
Conclusion
Square feet to square meters is one of the easiest conversions to memorize, and the exact factor (0.09290304) has not changed since 1959. For occasional conversions, the UtilBoxx Area Converter is private, free, and works offline once loaded. For batch work, Python and the `units` CLI handle thousands of values without leaving the terminal. And for one-offs, Google or a voice assistant gives an instant answer.
The mental shortcut: 1 m² ≈ 10.76 sq ft (about 11), and 1,000 sq ft ≈ 93 m². With these two anchors, you can sanity-check any real estate listing in your head.
