Common questions
How do I calculate cubic yards?
Multiply length × width × depth in feet to get cubic feet, then divide by 27. Depth is usually measured in inches, so divide inches by 12 first.
How many cubic feet are in a cubic yard?
27. A cubic yard is 3 ft × 3 ft × 3 ft.
How much does a cubic yard cover?
324 sq ft at 1" deep, 162 at 2", 108 at 3", 81 at 4", and 54 at 6".
How do I convert cubic yards to tons?
Multiply by the material's weight per yard: about 1.35–1.5 for gravel and sand, 1.0–1.2 for topsoil, 0.25–0.4 for mulch, and about 2 for concrete.
