For the most part, the only time you’ll use square yards is to measure and order carpeting. Although it may sound complicated, square yards is pretty simple.
You just take your square feet measurement and multiply it by a conversion factor. In the case of square yards, you just multiply your square foot measurement by 0.111111.
As an example, 550 square feet X 0.11111 = 61.1 square yards. Remember, when ordering carpeting for your DIY home improvement project, you need to order in full amounts and account for waste. So, in this case, you would order about 70 square yards (61.1 X 1.15 = 70.1 square yards).
You can also take your square foot measurement and divide it by 9 (There’s 9 square feet in 1 square yard). This is a bit easier to remember and calculate.
