You need a depth to convert area to volume
Square feet measure area (2D); cubic yards measure volume (3D). You cannot convert between them without a depth. The converter above assumes a 1-foot depth. For real projects, multiply by your actual depth:
Cubic yards = Square feet × Depth (feet) ÷ 27
For example, 100 sq ft at 4 inches (0.333 ft) deep: 100 × 0.333 ÷ 27 = 1.23 cubic yards. Use our cubic yard calculator for project-specific calculations with depth.
