Square Meters to Square Feet Converter — Convert m² to ft² (Exact: 1 ft² = 0.09290304 m²)
Accurate square meters (m²) to square feet (ft²) converter using the exact international foot definition (1 ft = 0.3048 m ⇒ 1 ft² = 0.09290304 m²). Built for real estate listings, architecture, flooring, facility planning, landscaping, and construction takeoffs. Includes exact formulas, step-by-step examples, precision guidance, expanded reference tables, and in-depth FAQs.
Exact bases: 1 ft = 0.3048 m ⇒ 1 ft² = 0.09290304 m². Therefore ft² = m² ÷ 0.09290304 (≈ m² × 10.7639104167). See all area metric conversion calculators.
About Square Meters to Square Feet Conversion
The square meter (m²) is the SI unit for area, used across architecture, engineering, planning, and building codes worldwide. The square foot (ft²) is common in US real estate, fit-outs, and retail programs. Converting square meters to square feet helps teams review plans, leases, and material takeoffs in the unit their stakeholders expect—without sacrificing SI accuracy.
Because the international foot is exactly defined, the area constant is exact too: 1 ft² = 0.09290304 m². That guarantees your conversions match CAD, BIM, spreadsheets, and permit forms when you round once at display time. Keep a single canonical unit (often m² for code and engineering), and compute ft² on the fly for US-facing reports and listings.
Typical practice: store area_m2 in your database, compute area_ft2 for UIs, and publish a short methods note with constants and rounding policy.

What is a Square Meter (m²)?
One square meter is the area of a square with 1-meter sides. It’s the basis of most international building and planning standards and composes neatly with other SI units—useful for loads (kN/m²), lighting (lux = lm/m²), and energy metrics (kWh/m²·yr).
What is a Square Foot (ft²)?
A square foot is the area of a square with 1-foot sides. Under the modern definition, 1 ft = 0.3048 m exactly, giving 1 ft² = 0.09290304 m² exactly. Though US projects often report floor areas in ft², many technical documents keep m² canonical to align with calculations and codes.
Step-by-Step: Converting m² to ft²
- Read the area in square meters (m²) from your plan, schedule, or takeoff.
- Divide by 0.09290304 to convert to square feet (ft²).
- Round once at presentation according to your policy (e.g., whole ft² for listings; 1–2 decimals for takeoffs).

Precision, Rounding & Significant Figures
Operational rounding
For marketing and MLS listings, whole ft² is common; for quantity takeoff and procurement, 1–2 decimals in ft² or 0.1 m² provide clarity without clutter. Store precise values; round once at presentation to keep PDFs, invoices, and dashboards in agreement.
Consistent documentation
Use explicit field names like area_m2 and area_ft2. Add a methods note: “Exact bases: 1 ft = 0.3048 m; 1 ft² = 0.09290304 m². ft² = m² ÷ 0.09290304. Round once on output.” Consistency prevents confusion when teams collaborate across regions and vendors.

Frequently Asked Questions
What is the exact formula to convert square meters to square feet?
Use the exact relationship for the international foot: 1 ft = 0.3048 m, therefore 1 ft² = (0.3048 m)² = 0.09290304 m². To convert m² → ft², divide by 0.09290304 (or multiply by ≈ 10.7639104167). The reverse is m² = ft² × 0.09290304. Because these constants are exact, results are reproducible across drawings, BIM models, and spreadsheets.
Why are area conversions not the same as length conversions?
Area is two-dimensional. When you move from meters to feet you square the length factor. Since 1 m ≈ 3.280839895 ft, squaring gives 1 m² ≈ 10.7639104167 ft². Forgetting to square is a common error that inflates/deflates areas by a factor of 3.28 instead of 10.76.
How should I round square footage for listings and contracts?
Keep full precision internally and round once on output. Real estate listings often use whole ft²; construction takeoffs may show 1 decimal; engineering reports can carry 2–3 decimals. State your rounding rule (e.g., “display whole ft²; calculations exact”) to avoid discrepancies between drawings and invoices.
What’s the difference between usable area, gross area, and carpet area?
These are scope definitions, not unit differences. Usable or net areas exclude circulation and services; gross includes them; ‘carpet area’ is an Indian market term for floor surface within internal walls. Our converter only changes units; the takeoff scope must be defined by your standards, lease, or code.
Can I sum mixed units like m² and ft² in one column?
Avoid mixing. Normalize to one canonical unit (commonly m² for design and code or ft² for US-centric reporting), perform all math, then convert and round once for presentation. Mixing units in the same column is a leading cause of audit failures.
Do I need to worry about the US survey foot for area?
Modern practice uses the international foot (exactly 0.3048 m). Legacy US survey foot data can differ slightly (2 ppm). Unless your project explicitly requires survey-foot coordinates, use the international definitions above for consistent m² ↔ ft² conversions.
Any tips to avoid double-rounding in exports?
Centralize the conversion utility, keep numbers at full precision through your pipeline, and round at the very last step (UI or export). Add unit-suffixed field names (e.g., area_m2, area_ft2) and include a methods note with constants and rounding policy.
How can I validate my conversion pipeline automatically?
Create regression pairs such as 1 m² = 10.7639104167 ft², 100 m² = 1076.39104167 ft², 1 ft² = 0.09290304 m². Test both directions in CI to catch accidental constant edits or formatting regressions early.
Tips for Working with m² & ft²
- Keep SI (m²) canonical for design, code checks, and analytics; compute ft² for US-facing documents.
- Publish a single rounding rule and reuse it across plan schedules, PDFs, and exports.
- Document whether areas are net/usable or gross; unit conversion does not define scope.
