Cubic Yard Calculator
Enter the length, width, and depth in feet to calculate how many cubic yards of material you need.
How to Calculate Cubic Yards
Formula
- Convert depth from inches to feet: depth_ft = depth_in / 12
- Calculate cubic feet: ft³ = length × width × depth_ft
- Convert to cubic yards: yd³ = ft³ / 27
Common Uses
- Concrete slabs and footings
- Mulch and topsoil for landscaping
- Gravel driveways and paths
- Sand for playgrounds and sandboxes
