Square Feet to Square Meters Converter (ft² ↔ m²)
Converting square feet (ft²) to square meters (m²) is the most common unit conversion in international real estate. The exact factor is 1 ft² = 0.09290304 m², derived from the internationally defined foot (0.3048 m). Whether you're comparing a U.S. MLS listing with a European property portal, filing a cross-border mortgage, or pricing a commercial lease for international tenants, this calculator handles both directions instantly.
1 square foot = 0.09290304 square meters (exact, by international definition). To convert ft² to m², multiply by 0.0929. To convert m² to ft², multiply by 10.7639. Example: 1,000 ft² = 92.90 m²; 100 m² = 1,076.39 ft².
When to use this calculator
- Comparing a U.S. MLS listing (in ft²) with a European property portal (in m²) to evaluate price-per-area before making an offer.
- Drafting a commercial lease with international tenants whose home country uses metric units.
- Filing a U.S. property tax appeal where comparable international sales evidence is presented in square meters.
- Preparing architectural documents for a U.S. property to be submitted to a foreign permitting authority requiring metric measurements.
- Valuing a vacation rental on Airbnb or Booking.com where European and South American travelers expect room sizes in m².
Worked Example
- Input: 1,500 ft²

How it works
2 min readHow to Convert Square Feet to Square Meters
The conversion is derived from the exact definition of the international foot: 1 foot = 0.3048 m (exact, since the International Yard and Pound Agreement of 1959). Squaring gives:
1 ft² = (0.3048 m)² = 0.09290304 m² [exact]
Formula — ft² to m²:
m² = ft² × 0.09290304
Formula — m² to ft²:
ft² = m² × 10.76391> Example 1: 1,500 ft² → 1,500 × 0.09290304 = 139.35 m²
> Example 2: 75 m² → 75 × 10.76391 = 807.29 ft²

Common Real-World Examples
International Home Purchase
A buyer from Germany is considering a home listed at 2,350 ft² on Zillow:
m² = 2,350 × 0.09290304 = 218.32 m²
Price: $750,000 ÷ 218.32 m² = $3,436/m²This lets the buyer benchmark against Munich prices (~€8,000–10,000/m²) and recognize the U.S. property is significantly cheaper per unit area.
Commercial Lease Negotiation
A U.S. landlord quotes 4,500 ft² of office space. The tenant's lawyer drafts the lease in metric:
m² = 4,500 × 0.09290304 = 418.06 m²
Rent: $45/ft² × 4,500 = $202,500/yr → $484.41/m²/yr---
Common Mistakes
1. Using 10 as a shortcut: Rounding 10.764 to 10 introduces a 7.6% error — on a 200 m² property, that's a 152 ft² discrepancy.
2. Applying the linear factor (0.3048) to areas: 1,000 ft² × 0.3048 = 304.8 — this is wrong by 3.3×. Always use 0.09290304 for areas.
3. Ignoring measurement standards: U.S. listings use Gross Living Area (includes walls); European listings often use net habitable area. Unit conversion does not fix this difference.
4. Rounding intermediate steps: Always convert first, then round the final result.
Frequently asked questions
What is the exact conversion factor from square feet to square meters?
1 ft² = 0.09290304 m² exactly. This is derived by squaring the internationally defined linear foot (0.3048 m), established by the International Yard and Pound Agreement of 1959 and unchanged since. The inverse is 1 m² = 10.76391 ft².
How many square meters is 1,000 square feet?
1,000 ft² = 92.90 m² (1,000 × 0.09290304). This is a typical small 2-bedroom apartment in the U.S., roughly equivalent to a 90–95 m² flat in European listings.
How many square feet is 100 square meters?
100 m² = 1,076.39 ft² (100 × 10.76391). In practical real estate contexts, this is typically quoted as 1,076 ft². A 100 m² apartment corresponds roughly to a 2–3 bedroom unit by U.S. standards.
How do I quickly convert square feet to square meters in my head?
Multiply by 0.093 (or divide by 10.76). For rough mental estimates, dividing by 10 gives a fast approximation — but remember that introduces a 7.6% error. For example: 2,000 ft² ÷ 10 = 200 m² (rough), but the correct answer is 185.81 m². Use this calculator for anything requiring accuracy.
Why do real estate listings in different countries show such different numbers for the same property?
Two reasons: (1) unit difference — 1 m² = 10.76 ft², so U.S. numbers are always ~10.76× larger; (2) measurement standards differ. The U.S. uses Gross Living Area (includes interior walls); Germany's Wohnfläche and France's loi Carrez use net habitable area, sometimes excluding rooms below a ceiling-height threshold. A proper comparison requires both a unit conversion AND a standards adjustment.
Does the IRS require square footage or square meters?
The IRS uses square feet (ft²) for U.S. domestic purposes — for example, the home office deduction (Form 8829) is calculated as a ratio of office ft² to total home ft². For foreign property reported on Form 3520 or FBAR disclosures, no specific unit is mandated, but accuracy is required.
What is the median U.S. home size in square meters?
According to the U.S. Census Bureau's 2022 Characteristics of New Housing, the median newly completed single-family home was 2,299 ft² = 213.6 m². The average was slightly higher at 2,480 ft² = 230.4 m².
How do I convert price per square foot to price per square meter?
Multiply the price per ft² by 10.76391. Example: a commercial lease at $35/ft²/year equals $35 × 10.76391 = $376.74/m²/year. Conversely, divide price per m² by 10.76391 to get price per ft². This is critical when comparing U.S. office lease rates against European benchmarks.
Are square feet still legal in the United States?
Yes. The U.S. officially designates the metric system as preferred (Metric Conversion Act of 1975), but customary units including square feet remain fully legal and are standard in real estate, construction, and property law. NIST publishes official conversion factors in NIST Handbook 44 and Special Publication 811.
