Before we start converting measurements, it’s essential to understand the difference between square feet and cubic feet. Square footage is a measure of area, while cubic footage is a measure of volume.
The image above shows the difference between the two measurements. Because these are completely different types of measure, you’ll need some additional data to convert between the two. In order to convert either way, you’ll need the height of the space.
Square Ft to Cubic Ft Formula
The volume in cubic feet is equal to the area in square feet times the height in feet.
For example, let’s calculate the cubic footage of a 100 square foot area that is 8 feet high.
volume = 100 sq ft × 8 ft
