How to Use the Cubic yard Calculator
- Measure the length and width of the area.
- Enter the depth or thickness you need and choose a unit for each measurement.
- Add waste or extra material when the job calls for it, then review the volume estimate.
Cubic yard Calculation Formula
Convert all dimensions to feet, multiply length by width by depth, then divide cubic feet by 27 to get cubic yards. One cubic foot equals approximately 0.0283 cubic meters.
Worked Example
A 10 ft by 10 ft area covered to 4 inches has a base volume of 33.33 cubic feet, or about 1.23 cubic yards, before any waste allowance.
How Much Cubic yard Do I Need?
A cubic yard is a volume unit, not a weight. Use the result to compare supplier quotes for bulk materials, and ask whether a delivery is sold by loose volume, compacted volume, or truck capacity.

Frequently Asked Questions
What does the cubic yard calculator measure?
Convert rectangular dimensions into cubic yards, cubic feet, and cubic meters.
Which units can I use?
Enter each dimension in inches, feet, yards, centimeters, or meters. The results are shown in cubic feet, cubic yards, and cubic meters.

How many cubic feet are in one cubic yard?
One cubic yard equals 27 cubic feet. The cubic yard calculator makes this conversion automatically after calculating the volume from your dimensions.
Can cubic yards be converted directly to tons?
Not without the material density. Cubic yards measure volume, while tons measure weight; multiply the volume by a verified density for the specific material and moisture condition.
