Square feet to square meters formula
m² = ft² × 0.09290304
The international foot is defined as exactly 0.3048 meters. A square foot is that length squared, so 0.3048 × 0.3048 = 0.09290304. Multiply any square-foot area by 0.09290304 to get square meters. To go the other way, divide by 0.09290304, which is about 10.7639 square feet in one square meter, or open the square meters to square feet converter.

Worked example
A room that is 12 feet long and 15 feet wide covers 12 × 15 = 180 square feet. Apply the exact factor: 180 × 0.09290304 = 16.7225472 square meters. The same multiplication scales an apartment: 1,200 × 0.09290304 = 111.483648 square meters. Type 180 or 1200 into the square-foot field to see the live result, then edit the square-meter field if you need the reverse.
International foot, not the old survey foot
This factor comes from the international foot used for everyday length: 1 inch is exactly 25.4 millimeters, and 12 inches make exactly 0.3048 meters. Squaring an exact length gives an exact area, which is why 1 ft² is 0.09290304 m² with no remainder.
It is not the former US survey foot of 1200/3937 meter. That older length squares to about 0.0929034116 square meters, roughly four parts in a million more than the international square foot. For floor plans, furniture and current property listings, use 0.09290304. If a land record still says it uses the survey foot, convert with the factor named in that record.
Rooms, listings and what this does not convert
Square feet show up on many US housing listings. Square meters show up on plans and listings in metric countries. Changing the unit does not change the floor, and it does not decide whether the source measured internal area, included walls, or followed a local market rule. Compare two listings only after you know which area each one describes.
A foot by itself is a length. A square foot is an area. A cubic foot is a volume. A hallway described as 40 feet is not 40 square feet, and a 40 cubic foot carton is not 40 square feet of floor. Measure length and width in the same unit, multiply, then convert. A bedroom 10 feet by 12 feet is 120 square feet, or 11.1483648 square meters. Values are calculated in your browser and are not submitted with the conversion.
Frequently asked questions
How many square meters are in one square foot?
One square foot equals exactly 0.09290304 square meters. The international foot is exactly 0.3048 meters, and 0.3048 multiplied by 0.3048 is 0.09290304.
How do you convert square feet to square meters?
Multiply the area in square feet by 0.09290304. For example, 100 square feet is 9.290304 square meters. Enter a value in either field of the converter above to recalculate at full precision.
What is 1,000 square feet in square meters?
1,000 square feet equals exactly 92.90304 square meters. A 1,200 square foot apartment equals 111.483648 square meters using the same factor.
How do I convert square meters back to square feet?
Divide the square-meter value by 0.09290304. One square meter is about 10.7639 square feet. You can also edit the square-meter field above or open the sqm to sqft converter.
Does this converter use the US survey square foot?
No. This page uses the international foot of exactly 0.3048 meters. The former US survey foot, 1200/3937 of a meter, squares to about 0.0929034116 square meters, roughly four parts in a million larger. Use the international factor for current floor plans and product sizes. If an older land survey names the survey foot, follow that record instead.
How do I convert a room measured in feet?
Multiply length by width in feet first, then convert that area. A room 10 feet by 12 feet is 120 square feet, which equals 11.1483648 square meters. A lone length in feet, or a volume in cubic feet, is not a floor area and should not be entered here.
