How to Convert Square Feet to Cubic Yard

To calculate cubic yards given an area in square feet, you’ll also need the height or depth of the space/object in question. This is because these are different units of measure, so to convert one from the other, you need the height.

Square feet measure the area of a space, while cubic yards measure its volume.

To convert, you can use a formula.

Square Feet to Cubic Yards Formula

Thus, the volume of a space in cubic yards is equal to the area of the base in square feet times the height in feet, divided by 27. Essentially, you’re calculating the volume in cubic feet, then by dividing by 27, you’re converting the result to cubic yards.

If you don’t know the square footage, you can always use our square footage calculator, or if you know the length and width of the space, you can use this formula:

Steps to Convert

Now that you know the conversion formula, follow these steps to convert square feet to cubic yards.

Step one: calculate the square footage of the space by multiplying the length and width.

Step two: calculate the cubic footage of the space by multiplying the square footage by the height or depth in feet.

Step three: calculate the cubic yardage of the space by dividing the cubic footage by 27.

How to Convert Cubic Yards to Square Feet

You can convert cubic yards back to square feet by reversing the steps above. Of course, you’ll need to know the conversion formula.

Cubic Yards to Square Feet Formula

The area in square feet is equal to the volume in cubic yards times 27, divided by the height in feet.
