Square Feet to Square Meters

Convert floor area between US customary and metric units.

Square feet to square meters: multiply by 0.09290304. For example, 100 sq ft = 9.290304 sq m. To convert back, divide by 0.09290304.

THE DETAILS

Good measurements make a better starting point.

Convert square feet to square meters

One square foot is exactly 0.09290304 square meters. Multiply square feet by 0.09290304 to convert to square meters. For the reverse conversion, divide square meters by 0.09290304, or multiply by approximately 10.7639. Keep enough decimal places during a calculation and round only the displayed answer.

QUICK EXAMPLE100 sq ft × 0.09290304 = 9.290304 sq m

Rounded to two decimal places, the area is 9.29 m².

Why the conversion factor is squared

A foot is 0.3048 meters. An area has two dimensions, so square the length factor: 0.3048 m × 0.3048 m = 0.09290304 m² per square foot. This is why the area factor is not 0.3048. Multiplying a square-foot value by the length factor would convert only one dimension and produce the wrong unit.

For a rectangular room, you may either convert the finished area or convert both dimensions before multiplying. A room that is 10 ft by 12 ft has 120 sq ft. Then 120 × 0.09290304 = 11.1483648 m², or about 11.15 m². Alternatively, 10 ft is 3.048 m and 12 ft is 3.6576 m; multiplying those dimensions gives the same unrounded area.

Area units are not length units

Square feet and square meters measure area, not the length of a wall. Write units with the result: 120 sq ft or 11.15 m². If a project plan lists only “meters,” check whether it means a side length or square meters of floor area. The two are not interchangeable.

Where this conversion helps

Metric and US customary units may appear together in property listings, renovation plans, product specifications, rental documents and online conversations. Converting to one unit lets you compare areas consistently. A converted area does not certify an official property measurement; conventions for reporting a home’s area can differ by jurisdiction, building type and purpose.

For product purchases, check the unit on the package. Coverage may be stated in square feet per box or square meters per package. If you convert coverage for comparison, use the same factor and do not round in the middle of a box calculation. The product’s printed coverage is the relevant value for ordering.

Rounding for practical use

For a quick comparison, two decimals are usually easy to read, but do not discard the precision if you will use the number in another calculation. For example, convert the full measured area, calculate the requested allowance or price, then round the final displayed result. An area estimate can still be approximate even when the unit conversion factor is exact, because the original measurements may have been rounded or taken from an irregular room.

Use the room calculator to find the original area or the square-foot to square-yard converter when working with carpet or another quote that uses square yards.
