Convert square meters to square feet
Type a value in either box, and the answer shows it in the other unit as you type.
- Square feet (ft²)
- 10.76391
1 m² = 10.76391 ft².
Square feet (ft²): 10.76391. 1 m² = 10.76391 ft².
Square feet (ft²) by square meters (m²)
How to calculate
Converts square meters (m²) to square feet (ft²) and back, with the exact unit definitions.
Example with the default inputs (Square meters (m²) 1): 1 m² = 10.76391 ft².
Formula: ft² = m² × 10.7639104167 (the same as m² ÷ 0.09290304)
- 1 square meter = 10.7639104167 square feet, from the exact definitions in NIST SP 811.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up; an answer of 1 billion or more shows at most 15 significant digits.
