What This Converter Does
This tool converts an area measured in square inches (in²) into square feet (ft²). It's handy whenever you have dimensions in inches but need to report or compare areas in square feet â for example flooring, tiling, fabric, glass panels, or signage.
How to Use It
Enter the area in square inches into the input box and the converter instantly returns the equivalent in square feet. If you only have length and width in inches, multiply them first (length Ă width) to get square inches, then enter that value.
The Formula Explained
One foot equals 12 inches, so one square foot is \(12 \times 12 = 144\) square inches. To convert, simply divide the square-inch value by 144:
$$\text{ft}^2 = \dfrac{\text{in}^2}{144}$$
This is an exact conversion â there is no rounding error in the constant.
Worked Example
Suppose you have a tabletop that measures 1,440 square inches. Divide by 144:
$$1{,}440 \div 144 = 10$$So the tabletop is 10 square feet. As another example, a 288 in² panel equals \(288 \div 144 = 2\) ft².
FAQ
How many square inches are in a square foot? Exactly 144 square inches make up one square foot.
How do I convert back from square feet to square inches? Multiply the square-foot value by 144 (\(\text{ft}^2 \times 144 = \text{in}^2\)).
Does this work for any shape? Yes. Area conversion is independent of shape â as long as you know the total area in square inches, dividing by 144 gives square feet.
