Cubic Feet Calculator
Calculate volume from length, width and height, convert mixed units, and see practical capacity estimates instantly.
Add length, width and height using feet, inches, yards, metres or centimetres.
The calculator converts all dimensions to feet and multiplies them together.
See cubic feet plus cubic inches, yards, metres, litres and gallons.
Your dimensions create 720 cubic feet of total space. This is useful for storage, room capacity, shipping, HVAC, concrete and material planning.
Volume = Length × Width × HeightAll three dimensions must use the same base unit before multiplication. This calculator converts each value to feet first, then calculates cubic feet.
Multiply length by width by height after converting all three measurements to feet. For example, 10 ft × 8 ft × 9 ft = 720 ft³.
Results are estimates generated locally in your browser from standard geometry, material yield and waste assumptions. They are for planning purposes only, not engineering, structural, code or supplier advice. Confirm dimensions, material strength, delivery constraints and local building codes with a licensed professional before purchasing or building.

Yes. Select a separate unit for each dimension. The calculator converts each value to feet before calculating the final volume.
One cubic yard equals 27 cubic feet because 3 ft × 3 ft × 3 ft = 27 ft³.
Results depend on accurate dimensions and describe rectangular volume. Irregular shapes, wall thickness, packing gaps, compaction and material waste may require extra allowance.
