Area conversions carry a trap that catches people who are perfectly comfortable with length: the factor is squared. There are 3.28 feet in a metre but 10.76 square feet in a square metre, and using the linear factor is the most common error in property arithmetic. Beyond that, land is measured in whatever the local convention prescribes — acres, hectares, and across South Asia bigha, katha and gaj — so the same plot is routinely described in two units that need reconciling.

To go the other way, use square foot = square meter ÷ 0.09290304.

About these units

The square foot remains the standard for property area in the US, India and much of the Middle East. There are 10.764 square feet in a square metre — not 3.28, a mistake that comes from squaring the linear factor only once.

The square metre is the standard unit of floor area worldwide, and the basis of both the hectare and the price-per-unit-area figures used in property.

Square Foot is also written square feet, sq ft, sqft, ft2 and ft^2. Square Meter is also written square metre, square metres, sq m, sqm, m2 and m^2.
