How to calculate cubic feet
Cubic feet is a unit of volume. To calculate the volume or capacity of an item or space in cubic feet you will first need to measure its length, width and height in either feet, inches (or a combo of both),centimeters, meters or yards. Once you have those measurements, you apply some multiplication as follows...
Calculating cubic feet for different units (formulae)
Let's look at each of these in turn.
Calculating cubic feet from measurements in feet
If you have measured the width, length and height of your item in feet then the calculation process is straight forward: Simply multiply the 3 figures together.
As an example, let's say you're looking for the capacity of a box thatmeasures 5ft by 3ft by 2ft. Multiplying those 3 figures together gives you a total cubic feet value of 30ft3.
Should you have already calculated your square footage, you simply need to multiply this figure by the height measurement.

As an example, let's say you're looking for the capacity of a box that measures 55" x 30" x 15". Multiplying those 3 figures together gives you a total cubic inches value of 24750in3. To convert that figure to cubic feet we divideit by 1728, giving a total of 14.323ft3.
Calculating cubic feet from centimeters
If you have measured the dimensions of your item in centimeters (cm) then do the following:
Calculating cubic feet from yards
If you have measured the dimensions of your item in yards then do the following:
