How to Convert Square Foot to Square Meter
- 1 ft² = 0.09290304 m²
- 1 m² = 10.76391042 ft²
- Example: convert 15 ft² to m²: 15 ft² = 15 × 0.09290304 m² = 1.3935456 m²
Formula
m² = ft² × 0.09290304
or m² = ft² ÷ 10.76391041671
Derivation from SI units:
- 1 ft² = (0.3048 m)² = 0.09290304 m²
- 1 m² = 1 m × 1 m
Both units are defined exactly, so the factor is exact. Square Foot definition: square foot; Square Meter definition: square meter.
Worked examples
- A 1500 ft² house is 139.35456 m².
1500 ft² × 0.09290304 = 139.35456 m² - The 4 ft² face of a 24 × 24 in filter is 0.37161216 m².
4 ft² × 0.09290304 = 0.37161216 m²
