What is the conversion ratio to change square feet into yards?

To change square feet into square yards, you must understand the relationship between these two units of area. One square yard consists of a square that is one yard on each side. Since there are 3 feet in a yard, when calculating area, you need to square the conversion factor.

In this case, the conversion factor is 3 feet per yard. Therefore, when converting square feet to square yards, you square the conversion factor:

3 feet × 3 feet = 9 square feet in a square yard.

Consequently, to convert square feet into square yards, you divide the number of square feet by 9. This means that when you want to find out how many square yards are in a certain number of square feet, you take the total square footage and divide it by 9, which is why this option is correct.
