Converting inches to square feet requires two dimensions, typically something like "length" multiplied by "width" both measured in inches, and the product gives you square inches. Once you have square inches, divide by 144 to get square feet.
The same idea applies to feet and square feet, but you don't have to convert anything when you get square feet. Take the two dimensions measured in feet, multiply them together and you get square feet.
