Square Feet to Square Meters Calculator (ft² to m²) with Formula
Convert square feet to square meters: m² = ft² × 0.0929. Example: 1,000 ft² × 0.0929 = 92.9 m². Reverse (m² to ft²): ft² = m² × 10.764. Use our ft² to m² calculator for instant conversion without arithmetic.
The Exact Conversion Factor
1 foot = 0.3048 metres exactly (by international treaty since 1959). Therefore:
1 ft² = 0.3048² = 0.09290304 m² exactly.
In practice, use 0.0929 (4 significant figures) for property measurements.
Quick Reference Conversion Table
| Square Feet (ft²) | Square Meters (m²) | Approx. Room Size |
|---|---|---|
| 50 | 4.65 | Small bedroom |
| 100 | 9.29 | Double bedroom |
| 200 | 18.58 | Large living room |
| 500 | 46.45 | Studio apartment |
| 1,000 | 92.90 | 1-bed apartment (US) |
| 1,500 | 139.35 | 2-bed apartment |
| 2,000 | 185.81 | 3-bed house |
| 2,500 | 232.26 | Large 4-bed house |
| 5,000 | 464.52 | Large commercial space |
| 10,000 | 929.03 | Retail store |
How to Convert Room Dimensions (Step by Step)
- Measure length in feet and width in feet
- Multiply: ft² = length (ft) × width (ft)
- Convert: m² = ft² × 0.0929
Example: Bedroom 14 ft × 11 ft
14 × 11 = 154 ft². Then 154 × 0.0929 = 14.31 m².
Example: House 2,200 ft²
2,200 × 0.0929 = 204.4 m². Or mentally: 2,200 ÷ 10 = 220, then subtract 7% → 220 − 15.4 ≈ 204 m².
Reverse: Square Meters to Square Feet
| Square Meters (m²) | Square Feet (ft²) |
|---|---|
| 10 | 107.6 |
| 20 | 215.3 |
| 50 | 538.2 |
| 100 | 1,076.4 |
| 200 | 2,152.8 |
| 500 | 5,381.9 |
Mental Shortcuts
- ft² ÷ 10 → overestimates m² by about 7%
- ft² ÷ 11 → underestimates m² by about 3%
- ft² × 0.093 → accurate to 0.1%
- Quick check: 100 ft² ≈ 9.3 m² (think: roughly 9 square meters per 100 square feet)
Why Different Countries Use Different Units
Square feet remain dominant in the US, Canada (mixed), and UK property markets. Square meters are standard in the EU, Australia, and most of the world. When comparing international real estate, always convert — European listings in m² often look small until you convert: a 75 m² Paris flat = 807 ft², which is a solid 1-bedroom by US standards.
