Square Feet to Square Meters
On this page
Multiply square feet by exactly 0.09290304 to obtain square meters. The area factor is the square of the exact linear relation 1 ft = 0.3048 m.
Direct answer
Multiply square feet by exactly 0.09290304 to obtain square meters. The area factor is the square of the exact linear relation 1 ft = 0.3048 m.
Method and required inputs
Square meters = square feet × 0.09290304. Reverse with square feet = square meters / 0.09290304.
Worked example
200 ft2 × 0.09290304 = 18.580608 m2, commonly displayed as 18.58 m2 when hundredths are appropriate.
Assumptions and limitations
The factor is exact, but source measurements and property-area definitions may not be. Converting a listing does not certify how its area was measured.
Checks and common errors
- Use the area factor, not 0.3048.
- Do not convert linear feet as square feet.
- Round after multiplying.
Frequently asked questions
Why is the factor not 0.3048?
Area uses two dimensions, so the linear factor is squared: 0.3048 × 0.3048 = 0.09290304.
