What this calculator does
Bulk landscape and construction materials are often sold by cubic yard. This tool calculates a rectangular volume from feet and inches, converts depth to feet and then divides cubic feet by 27 to return cubic yards.
What to know before you use the result
- One cubic yard equals 27 cubic feet.
- The result is geometric volume and does not account for compaction, settlement or density.
- Weight conversions require material-specific density.
Common mistakes to avoid
- Entering depth in inches as though it were feet.
- Using square footage alone when a volume calculation requires depth.
- Assuming one cubic yard weighs the same for every material.
