How to Use This Calculator
Enter your input values
Fill in all required input fields for the Cubic Yard Calculator. Most fields include unit selectors so you can work in your preferred unit system — metric or imperial, whichever matches your problem.
Review your inputs
Double-check that all values are correct and that you have selected the right units for each field. Incorrect units are the most common source of calculation errors and can produce results that are off by factors of 2, 10, or more.
Read the results
The Cubic Yard Calculator instantly computes the output and displays results with units clearly labeled. All calculations happen in your browser — no loading time and no data sent to a server.
Explore parameter sensitivity
Try adjusting individual input values to see how the output changes. This is a quick and effective way to develop intuition about how different parameters influence the result and to identify which inputs have the largest effect.

About Cubic Yard Calculator
Bulk construction materials like concrete, gravel, sand, mulch, and topsoil are sold by the cubic yard. This calculator converts your area dimensions and depth into cubic yards so you can order the right amount. One cubic yard equals 27 cubic feet -- a cube measuring 3 feet on each side. The conversion from linear measurements to cubic yards is straightforward but frequently causes errors because depth is often given in inches while length and width are in feet. This calculator handles the unit conversion automatically. Whether you are filling a garden bed with topsoil, ordering gravel for a driveway, or pouring a concrete slab, cubic yards is the unit your supplier needs.
The Math Behind It
Formula Reference
Cubic Yards
CY = L x W x (D/12) / 27
Variables: L and W in feet, D in inches. 1 cubic yard = 27 cubic feet.
Worked Examples
Example 1: Garden bed 12 x 4 ft, 6 inches deep
Length = 12 ft, Width = 4 ft, Depth = 6 in
You need approximately 0.89 cubic yards (round up to 1 cubic yard when ordering).
Common Mistakes & Tips
- !Forgetting to convert depth from inches to feet before calculating volume.
- !Confusing cubic feet with cubic yards (1 cubic yard = 27 cubic feet, not 3).
- !Not rounding up to a practical ordering quantity.
- !Using the wrong depth -- measuring the space before or after compaction makes a difference.

Frequently Asked Questions
How many cubic feet in a cubic yard?
There are 27 cubic feet in one cubic yard (3 x 3 x 3 = 27).
How many wheelbarrow loads in a cubic yard?
A standard 6-cubic-foot wheelbarrow holds about 6 cubic feet. You would need about 9 wheelbarrow loads to move one cubic yard of material (27 / 6 = 4.5 per half, roughly 9 total allowing for practical fill levels).
