Square Feet to Cubic Yards Calculator
Convert between area (square feet) and volume (cubic yards) for construction and landscaping projects
Area ↔ Volume Conversion
Surface area to be covered
Depth of material layer or excavation
Conversion Results
Formula: Volume (yd³) = Area (ft²) × Depth (ft) ÷ 27
Calculation: 0.00 ft² × 0.00 ft ÷ 27 = 0.000 yd³
Key Conversion: 1 cubic yard = 27 cubic feet (3 ft × 3 ft × 3 ft)
Material Estimation Guide
Practical Examples
Flower Bed Project
Area: 9 ft × 6 ft = 54 ft²
Depth: 6 inches = 0.5 ft
Volume calculation: 54 ft² × 0.5 ft = 27 ft³
Convert to cubic yards: 27 ft³ ÷ 27 = 1.0 yd³
Result: Need 1 cubic yard of soil/mulch
Concrete Driveway
Area: 20 ft × 10 ft = 200 ft²
Thickness: 4 inches = 0.333 ft
Volume calculation: 200 ft² × 0.333 ft = 66.6 ft³
Convert to cubic yards: 66.6 ft³ ÷ 27 = 2.47 yd³
Result: Need 2.5 cubic yards of concrete
Gravel Path
Area: 100 ft × 3 ft = 300 ft²
Depth: 2 inches = 0.167 ft
Volume calculation: 300 ft² × 0.167 ft = 50.1 ft³
Convert to cubic yards: 50.1 ft³ ÷ 27 = 1.86 yd³
Result: Need 1.9 cubic yards of gravel
Key Conversions
Volume:
1 cubic yard = 27 cubic feet
1 cubic yard = 46,656 cubic inches
1 cubic yard = 764.55 liters
Area:
1 square yard = 9 square feet
1 square foot = 144 square inches
1 acre = 43,560 square feet
Length:
1 yard = 3 feet = 36 inches
1 foot = 12 inches = 0.3048 meters

Calculation Tips
Always order 10-15% extra material for waste and compaction
Convert all measurements to the same unit before calculating
Remember: 1 cubic yard = 27 cubic feet (3×3×3)
For irregular shapes, break into rectangles and add areas
Understanding Square Feet to Cubic Yards Conversion
What are Square Feet and Cubic Yards?
Square feet (ft²) is a unit of area measuring two dimensions (length × width).Cubic yards (yd³) is a unit of volume measuring three dimensions (length × width × height/depth).
Why Convert Between Them?
- •Calculate material quantities for landscaping projects
- •Determine concrete volume for slabs and driveways
- •Estimate soil, mulch, or gravel requirements
- •Plan excavation and fill projects
Conversion Process
Volume (yd³) = Area (ft²) × Depth (ft) ÷ 27
Area (ft²) = Volume (yd³) × 27 ÷ Depth (ft)
Step 1: Measure Area
Calculate or measure the surface area in square feet
Step 2: Measure Depth
Determine the depth/height/thickness in feet
Step 3: Calculate Volume
Multiply area × depth, then divide by 27
Why divide by 27? Because 1 yard = 3 feet, so 1 cubic yard = 3 × 3 × 3 = 27 cubic feet
