How to Calculate Cubic Yards
Formula
Cubic yards are the standard unit for ordering bulk materials like concrete, gravel, mulch, and soil. To calculate cubic yards, multiply length by width by depth (all in feet) and divide by 27.
This calculator accepts depth in inches for convenience since material depth is often specified in inches (e.g., 4 inches of gravel).
Common use cases:
- Ordering concrete for slabs and footings
- Calculating mulch or gravel for landscaping
- Estimating soil for raised garden beds
