When measuring area using the standard or imperial system, the most common units are either square feet or square yards. Square feet is a very common measurement when measuring the area of a house or apartment. However, while the United States uses primarily standard measurements, the rest of the world overwhelming uses metric measurements. Depending on the intended use of the measurements needed, it may be desirable to convert between the two. While the conversion from square feet to square yards is relatively straightforward and simply requires multiplying by 9, converting from square feet to square meters is somewhat more complicated.
Use a simple conversion factor. Converting directly from square feet to square meters is possible by simply using a conversion figure. The relationship between square feet and square meters is linear, meaning that no matter how many square feet you are working with, the ratio of square feet to square meters is the same. The conversion factor, out to four decimal places, is .0920. Multiply the number of square feet you have by this figure and you will have the equivalent number of square meters.
Double check. Depending on the project you are undertaking, it could be very important to make sure you don't inadvertently make a miscalculation by entering the wrong number on your calculator or by making some other otherwise trivial mistake. You can quickly double check your number from step 1 by first converting your square feet into feet. Do this by taking the square root of the square feet figure. Now multiply this number by .3048 (the conversion factor for feet to meters). Now, square this number to find square meters.
Compare the two figures. Compare the figures from Step 1 and Step 2. Unless you made a mistake in one of the calculations, you should have reached the same number. If you did, in fact, get the same result, you can feel confident in your results.
