Quick answer
Convert project dimensions into cubic yards for concrete, gravel, soil, mulch and other bulk materials. Use the working RenoMetric calculator below for the actual estimate, then use this page to check assumptions, package rounding and project-specific considerations.

Formula
Worked planning example
A volume of 81 ft³ equals exactly 3 yd³ because one cubic yard contains 27 cubic feet.
Common uses
- Concrete
- Gravel
- Topsoil
- Mulch and fill
How to get a better estimate
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Cubic Yard Calculator FAQ
How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard.
Can cubic yards convert directly to tons?
Not without density. Weight depends on the specific material, gradation and moisture content.
Should I round cubic yards before ordering?
Use the supplier’s order increments and the project allowance after calculating the raw geometric volume.
