You cannot convert square yards to cubic yards. One is a measure of area and the other is a measure of volume.
If you have a cube with edges 3 yards long the area of each face will be 3 x 3 = 9 square yards. The volume of the cube will be 3 x 3 x 3 = 27 cubic yards. Was it perhaps something along these lines that you meant?
