Cubic Feet
Learn how we calculated this below

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.

## How to Convert Square Feet to Cubic Feet

To convert square feet to cubic feet using the area and height, you’ll need to use a conversion formula.

### Square Ft to Cubic Ft Formula

You can use the following formula to convert square feet to cubic feet:

cu ft = sq ft × 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

You can also use our calculator to convert to cubic yards.

## How to Convert Cubic Feet to Square Feet

When you know the volume in cubic feet you can reverse the formula above to convert it to square feet.

### Cubic Ft to Square Ft Formula

This formula shows how to convert from a volume to an area measurement.

sq ft = cu ft ÷ 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
