Cubic Yards = Cubic Feet ÷ 27
Cost = Cubic Yards × Cost Per Cubic Yard
Square Feet to Cubic Yards Calculator
The Square Feet to Cubic Yards Calculator helps determine how much material is required for construction, landscaping, excavation, and concrete projects. It converts surface area and depth measurements into cubic yards, the standard unit used when purchasing concrete, gravel, sand, mulch, topsoil, and other bulk materials.
What Is a Cubic Yard?
A cubic yard is a unit of volume equal to a cube measuring 3 feet long, 3 feet wide, and 3 feet high.
1 Cubic Yard = 27 Cubic Feet
How To Calculate Cubic Yards
To determine cubic yards:
Cubic Feet = Square Feet × Depth (ft)
Cubic Yards = Cubic Feet ÷ 27
Common Uses
- Concrete slabs
- Driveways
- Patios
- Gravel installation
- Mulch projects
- Topsoil replacement
- Landscaping beds
- Excavation work
Example Calculation
Area = 500 sq ft
Depth = 4 inches
4 inches = 0.333 feet
Cubic Feet = 500 × 0.333 = 166.5
Cubic Yards = 166.5 ÷ 27 = 6.17 cubic yards
Material Coverage Guide
| Material | Typical Depth |
|---|---|
| Mulch | 2–4 inches |
| Topsoil | 4–6 inches |
| Gravel | 3–6 inches |
| Concrete | 4–6 inches |
| Sand | 2–4 inches |
Benefits of Using This Calculator
