Square Feet to Cubic Yards Calculator
Our sq. Ft to cubic yards calculator serves as an essential construction tool for transforming two-dimensional measurements into three-dimensional volume calculations.
When planning a garden bed that measures 20 square feet with a desired soil depth of 1.5 feet, the calculator would determine you need approximately 1.11 cubic yards of soil (20 × 1.5 ÷ 27 = 1.11 cubic yards).
Square Feet to Cubic Yards Formula
The formula can be expressed as: Cubic Yards = (Square Feet × Depth in feet) ÷ 27
- Multiply the area in square feet by the depth in feet
- This gives you cubic feet
- Divide the result by 27 (since 1 cubic yard = 27 cubic feet)

How do you convert square feet to cubic yards?
Consider a patio project covering 200 square feet that requires a 4-inch (0.333 feet) deep layer of gravel.
- Area × Depth = 200 × 0.333 = 66.6 cubic feet
- 66.6 ÷ 27 = 2.47 cubic yards of gravel needed
- 100 sq ft = 3.7 cubic yards
- 200 sq ft = 7.4 cubic yards
- 300 sq ft = 11.1 cubic yards
- 400 sq ft = 14.8 cubic yards
- 500 sq ft = 18.5 cubic yards
How many cubic yards is 500 square feet?
When working with 500 square feet for a standard 6-inch depth (0.5 feet) project:
Calculation:
- 500 × 0.5 = 250 cubic feet
- 250 ÷ 27 = 9.26 cubic yards
This volume could fill a medium-sized dump truck, highlighting the importance of accurate calculations for material ordering and cost estimation.
What is Square Feet and Cubic Yards
Square feet represents area measurement in two dimensions (length × width), commonly used for flooring, roofing, or land measurements. A square foot is the area of a square measuring one foot on each side.
Cubic yards measures volume in three dimensions (length × width × height), typically used for bulk materials like soil, concrete, or gravel. One cubic yard equals 27 cubic feet and represents the volume of a cube measuring one yard on each side.
