MATERIAL AND PROJECT ESTIMATES
Calculate rectangular volume in cubic feet and convert it to cubic yards and cubic meters.
Your result
Enter your values and select Calculate. Your result stays on this device.
Rectangular volume = length × width × height. One cubic yard is 27 cubic feet.
All three measurements are in feet and form a rectangular prism.
This volume calculator gives a direct rectangular-prism result in the units commonly used for U.S. home projects. Keep all measurements in feet before calculating.
Use case
Multiply three dimensions entered in feet and review the same rectangular volume in common U.S. project units before choosing a material-specific estimate.
Calculate a rectangular project volume and compare cubic feet, cubic yards, and cubic meters.

Volume Calculator helps you check a specific home projects question with figures that apply to you. Calculate rectangular volume in cubic feet and convert it to cubic yards and cubic meters. Multiply three dimensions entered in feet and review the same rectangular volume in common U.S. project units before choosing a material-specific estimate. Calculate a rectangular project volume and compare cubic feet, cubic yards, and cubic meters. The page keeps the method and limits visible so the result can be understood, compared, and checked instead of treated as an unexplained answer.
Prepare Length, Width and Height. Measure length, width, and height in feet. Enter decimal feet when a dimension includes inches. Review cubic feet and the converted cubic-yard value. Use a project-specific calculator when compaction, waste, or irregular shapes matter. Keep units, dates, currency, and time periods consistent.
The stated method is: Rectangular volume = length × width × height. One cubic yard is 27 cubic feet. Change one assumption at a time to see which input drives the result, then compare scenarios on the same basis.
All three measurements are in feet and form a rectangular prism. Check the input and rounding, then calculate again.
