Square Feet to Square Meters Converter

Multiply the square feet by 0.09290304. For 500 sq ft, that is 500 × 0.09290304 = 46.45 m². You can also divide by 10.7639. Pick "sq ft → m²" in the converter, enter the area, and it shows the result with the steps and a chart. The factor is exact, so a rounded result is the only source of small differences.

1 square foot equals exactly 0.09290304 square meters. That makes a square foot about 0.093 m², or 929 square centimeters. The factor comes from the foot itself: 1 ft is 0.3048 m, and 0.3048 × 0.3048 = 0.09290304. So how much is 1 sq ft in square meters? A little over nine hundredths.

One square meter is 10.7639 square feet (10.763910416709722 to more places), found by dividing 1 by 0.09290304. So 50 m² is 538.2 sq ft, 100 m² is 1,076.4 sq ft and 150 m² is 1,614.6 sq ft. Choose "m² → sq ft" in the converter to convert any area.

Multiply each by 0.09290304. 41 sq ft is 3.81 m², 160 sq ft is 14.86 m², 800 sq ft is 74.32 m², 2350 sq ft is 218.32 m² and 25000 sq ft is 2,322.58 m². For any other number, enter it in the converter with "sq ft → m²" selected.

A 12 ft by 12 ft room has 12 × 12 = 144 square feet, which is 144 × 0.09290304 = 13.378 square meters. The side of that room is 12 ft, or 3.66 m. Choose "Room L × W" in the converter, enter 12 and 12, and it gives the area in both units and in square yards.

You cannot, because feet measure a length and square meters measure an area. You need a second length. A room that is 13 ft by 10 ft is 130 sq ft, or 12.08 m². If 13 ft is the side of a square, the area is 13 × 13 = 169 sq ft, or 15.70 m². The room mode of the converter does this for you.

For a rectangle, multiply the length in meters by the width in meters. A room 4 m by 5 m is 20 m². If you measured in feet, multiply the length by the width in feet to get square feet, then multiply by 0.09290304. For a triangle, multiply the base by the height and divide by 2, and for a circle use π × radius².

Measure the length and width of each room from wall to wall in feet, and multiply them. Add the rooms together for the total. A 12 ft by 15 ft bedroom is 180 sq ft and a 10 ft by 10 ft office is 100 sq ft. Split odd shapes into rectangles. The square footage calculator adds several rooms and follows how home sizes are reported.

Area grows with the square of the length. A square that is 1 m on each side measures 3.2808 ft by 3.2808 ft, and 3.2808 × 3.2808 is 10.76 square feet. In the same way a square foot is 0.3048 × 0.3048 = 0.0929 m². Multiplying an area by the length factor, 3.28 or 0.3048, gives a wrong answer.

The international foot is exactly 0.3048 m. The US survey foot was 1200/3937 m, about 0.3048006 m, which is 2 parts per million longer. NIST superseded the survey foot with the international foot on January 1, 2023, and the results here use the international foot. The area difference is below one part in 200,000.

1,000 square feet is 92.903 m². A square with that area is about 31.6 ft on a side, which is 9.64 m. For a feel of the size, a 1,000 sq ft apartment is roughly a 25 ft by 40 ft space. The chart under the converter lists 10 to 10,000 sq ft.

Divide square feet by 9 for square yards, and by 43,560 for acres. 1,000 sq ft is 111.1 square yards and 0.023 acre. The converter shows square yards under the main result. For acres, hectares and lot sizes, use the square feet to acres converter.
