How to calculate cubic yards
Multiply length by width and depth to find volume in cubic feet. When depth is entered in inches, divide it by 12 first. Then divide cubic feet by 27.
Cubic yards = Length × Width × (Depth ÷ 12) ÷ 27
Cubic yard example
An area measuring 20 feet by 10 feet with a depth of 3 inches contains 50 cubic feet, or approximately 1.85 cubic yards.
Frequently asked questions
How many cubic feet are in one cubic yard?
27 cubic feet.
How do I convert cubic feet to cubic yards?
Divide cubic feet by 27.
What materials are commonly sold by the cubic yard?
Gravel, soil, mulch, sand and concrete are commonly measured or sold by volume.
Using this calculator effectively
This calculator converts length, width and depth into cubic yards, a common bulk-material unit. It is useful for soil, gravel, mulch, concrete and similar materials sold or delivered by volume.
Common uses
- Estimating bulk landscaping material.
- Calculating excavation or fill volume for a rectangular area.
- Converting a shallow depth measured in inches into cubic yards.
Tips for a better estimate
- Measure irregular areas in smaller rectangles and add the volumes together.
- Use finished or compacted depth when that is the project requirement.
- Add a material-specific allowance for compaction, settling or waste where appropriate.
