How to Convert Square Feet to Cubic Feet
TL;DR
To convert square feet to cubic feet, multiply the square footage by the height in feet.
cu yds = sq ft × heightft
Square feet are a two-dimensional measurement of the area of a space, while cubic feet are a three-dimensional measurement of volume.
The image below shows the difference between the two measurements.
Since they are completely different types of measurements, you need the height or depth to convert from a two-dimensional measurement to a three-dimensional one.
Therefore, to convert square feet to cubic feet, you’ll need the height or depth of the space/object and the conversion formula.
Square Feet to Cubic Feet Formula
You can use the following formula to convert square feet to cubic feet:
cu ft = sq ft × height
Thus, the volume in cubic feet is equal to the area in square feet times the height in feet. If you first need to calculate square feet, try our square footage calculator to find the area.
For example, let’s calculate the cubic footage of a 5 square foot area that is 2 feet high.
volume = 5 sq ft × 2 ft
volume = 10 cu ft
You can also use our calculator to convert square feet to cubic yards.
How to Convert Cubic Feet to Square Feet
As noted above, you need to know some additional information before you can convert cubic feet to square feet, since they measure different things. If you know the height or depth, then you can rearrange the formula above to convert cubic feet to square feet.
Cubic Feet to Square Feet Formula
You can use the following formula to convert cubic feet to square feet:
sq ft = cu ft ÷ height
So, the area in square feet is equal to the volume in cubic feet divided by the height in feet. Check out our cubic feet calculator to find the volume of a space.
For example, let’s calculate the square footage of an area in a 15 cubic foot volume that is 3 feet high.
area = 15 cu ft ÷ 3 ft
area = 5 sq ft
