# Square Feet to Cubic Feet Calculator

Enter square feet and the height of the space to calculate the total cubic footage. You can also convert from cubic feet to square feet if the height and volume is known.

## How to Convert Square Feet to Cubic Feet

Before we start converting measurements, it’s important 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.

Because these are completely different types of measure, we need some additional data to convert between the two. The calculator above uses the height and area to calculate the volume.

The following formula can be used to convert square feet to cubic feet:

volume = area × height

The volume in cubic feet is equal to the area in square feet times the height in 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

## How to Convert Cubic Feet to Square Feet

To find the square footage of an area when cubic footage and height are known, the formula above can be reversed. This formula shows how to convert from a volume to an area measurement.

area = volume ÷ height

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
