Formula
Volume (ft³) = Area (ft²) × Thickness (ft)
Volume (yd³) = Volume (ft³) ÷ 27
How to Convert Square Feet to Cubic Yards
To convert square feet to cubic yards, you need an additional measurement: the height or depth of the area. Once you have that measurement in feet, multiply it by the area in square feet to get cubic feet, then divide by 27 (since there are 27 cubic feet in a cubic yard).
Example Calculation
Let's say you have an area of 500 square feet with a depth of 6 inches (0.5 feet):
500 ft² × 0.5 ft = 250 ft³
250 ft³ ÷ 27 = 9.26 yd³
