How to convert square feet to square meters
Area factors are squared length factors. Acres here use international feet, not historical US survey feet.
Use x for the value in ft², b for the intermediate value in m², and y for the result in m².
m² = ft² × 0.09290304
Worked examples
10 ft² ≈ 0.9290304 m²
Step 1: (10 × 0.09290304) ≈ 0.9290304 m².
Step 2: 0.9290304 ÷ 1 ≈ 0.9290304 m².20 ft² ≈ 1.8580608 m²
Step 1: (20 × 0.09290304) ≈ 1.8580608 m².
Step 2: 1.8580608 ÷ 1 ≈ 1.8580608 m².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
