Square feet to square meters formula
n
By international agreement adopted in 1959, one international foot equals exactly 0.3048 meters. Because area represents two-dimensional space, the conversion factor is the square of the linear conversion factor (0.3048 × 0.3048 = 0.09290304).
nn
To convert square feet to square meters, multiply the square footage by 0.09290304, or divide the value by 10.76391.
nn
Exact Formula:
m² = sq ft × 0.09290304
n
Alternative Division Formula:
m² = sq ft / 10.7639104

Common mistakes when converting area
n
- n
- Using linear conversion factors: A common error is multiplying by 0.3048 (the linear conversion for feet to meters) rather than 0.092903. Linear conversions describe length, whereas area represents two dimensions (length × width).
- Over-rounding floor estimates: When ordering expensive materials like hardwood flooring, carpet, or ceramic tile, rounding 0.092903 to 0.1 introduces a ~7.6% surplus error. Always use at least four decimal places (0.0929) or multiply by 0.092903 before adding standard 10% wastage.
- Confusing gross internal area with net usable area: North American listings often quote gross exterior building dimensions, while European property records typically quote strictly usable living space (carrez law in France, DIN standards in Germany).
