Tip: Divide cubic feet by 27 to convert to cubic yards when ordering concrete or landscape material. One yard equals 27 cubic feet.
How to Use This Calculator
Measure the space
Record the length, width, and height of the area you are evaluating.
Choose the measurement unit
Select the unit that matches your measurements—feet, inches, yards, centimeters, or meters.
Review the volume conversions
Use the cubic feet result for shipping or storage, and refer to cubic yards, liters, and gallons for material orders.
Formula
Volume (ft³) = Length × Width × Height
Measurements are first converted into feet so that the formula produces cubic feet. Additional conversions use precise volume constants (for example 1 ft³ = 7.48052 gal).
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Cubic feet represent the interior volume of a rectangular space. Contractors, movers, HVAC designers, and DIY enthusiasts rely on cubic feet to estimate material needs, shipping capacity, and storage requirements.
Because projects rarely use a single unit system, this calculator converts the same volume into cubic yards for concrete pours, gallons for liquid storage, and liters for international teams. The consistent results save time compared with manual conversions and help eliminate rounding mistakes.
For irregular shapes, break the space into rectangles, calculate each volume separately, and add the totals. You can also pair this tool with the Gallon Calculator or Cubic Yards to Tons Converter for downstream planning.
Frequently Asked Questions
Can I enter measurements in different units?
Enter all dimensions using the same unit (feet, inches, yards, centimeters, or meters). The calculator converts them internally to feet before computing volume.
How do I handle irregular spaces?
Divide the shape into smaller rectangles or boxes, calculate the volume of each, and add them together. This ensures accurate totals even for complex rooms.
What can I do with the cubic feet result?
Use cubic feet to estimate storage capacity, HVAC requirements, shipping container fill, or conversions to cubic yards and gallons for material ordering.
Is this calculator suitable for metric projects?
Yes. Enter measurements in centimeters or meters and convert the result to cubic meters or liters instantly.
