Find the total volume in cubic feet for one or many areas. Each dimension has its own unit selector (in/ft/yd/m).
Cubic feet is length times width times height, all in feet. The unit selector converts inches, yards, meters or centimeters to feet for you. For round areas, the volume is pi times the radius squared times the depth. Divide cubic feet by 27 for cubic yards - shown below the total.
Use the cubic feet calculator when a project is quoted or packed by cubic foot. It is helpful for fill volumes, containers, raised beds, insulation cavities and other jobs where cubic yards are too coarse.
Start with the calculator that matches how your material is sold: area, length, volume, count, weight or electrical load. Enter one work area at a time, use the unit selector beside each measurement, then review the order quantity and cost fields before comparing supplier quotes.
Most calculators can save the current estimate in your browser, reload named estimates, print a copy, switch to dark mode or create a shareable link. Those tools are intended for planning and communication; always confirm final quantities, coverage rates, density, code requirements and pricing with the supplier or contractor responsible for the work.
