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
