Square Meters to Square Feet Converter (m² to ft²)

Most of the world measures floor space in square meters, from apartment listings in Seoul or Berlin to office leases and building plans, while American buyers, renters and contractors think in square feet. A square foot is exactly 0.09290304 m², the square of the international foot of 0.3048 m, so one square meter is about 10.7639 square feet.

The area factor is the square of the length factor, not the length factor itself. Multiplying square meters by 3.28, the number of feet in a meter, gives an answer about 70% too small; the area has to be multiplied by 3.28 twice. For a room plan in meters, either multiply length by width first and convert the area here, or convert each side to feet first: both routes give the same result.

How to use this tool

1. Type a value in the Square Meter box to see it in square feet, or type in the Square Foot box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Area converter.

Formula

ft² = m² ÷ 0.09290304

m² = ft² × 0.09290304

Both factors come from exact definitions: 1 square foot = 0.09290304 square meters and 1 square meter = 10.7639104167 square feet (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

84 m² × 10.7639104167 ≈ 904.168 ft²

1000 ft² × 0.09290304 = 92.90304 m²

Quick mental estimate

Multiply by 10, then add three quarters of the original: 84 m² → 840 + 63 = 903 ft². That is ×10.75, about 0.13% below the exact 10.7639, so the answer is about 1 ft² short of the true 904.2 ft².

Use the converter or the charts when the exact figure matters.

The two units

Square Meter (m²): The square metre is the SI unit of area, the area of a square 1 metre on each side. Floor space of homes and offices is given in square metres in most countries.

Square Foot (ft²): A square foot is the area of a square one international foot on each side, exactly 0.09290304 m² or 144 square inches. Historical areas based on the US survey foot use a slightly different factor.
