Square Feet to Cubic Feet (ft2 to ft3) Converter

Convert ft² into ft³ depending on the given height or depth.

Converting square feet (ft²) to cubic feet (ft³) is necessary when you want to calculate the volume of a three-dimensional object based on its area and height or depth.

For example, if you have the area of a floor in square feet and you want to calculate the volume of a room by multiplying the area with the height, you would need to convert the square feet measurement to cubic feet. This conversion allows you to accurately determine the amount of space enclosed by the room.

How to use this calculator?

  1. Enter the area in square feet.
  2. Enter the Height or Depth in feet.
  3. Get the volume in cubic feet from the "Result" section.

How to convert ft² to ft³?

To convert from square feet (ft²) to cubic feet (ft³), multiply the area by the height or depth:
Volume [ft³] = Area [ft²] * Height or Depth [ft]


For example, let's say you have an area of 100 ft² and a depth of 5 ft. To find the volume:

Volume [ft³] = 100 ft² * 5 ft = 500 ft³
