Feet can be used to describe the distance between two points, or the height of a person or object. Square feet, however, defines the total space covered by an object on a flat surface. For instance, when you measure the length of a room from one wall to another, you're working with feet; but when calculating the total space that room occupies, you use square feet.

In math and geometry, feet is a one-dimensional measurement. This means it only has length. Square feet, being a measure of area, is two-dimensional, encompassing both length and width. So, while you might describe a plot's length as 20 feet, its total area might be 200 square feet, considering its width.

Another way to think of the difference is in their multiplication. If you multiply a measurement in feet by another measurement in feet, the result is in square feet. For example, if a room is 10 feet by 20 feet, its area is 200 square feet.

Lastly, it's important to note that while feet is universally understood and applied in many situations, square feet is specifically related to areas. So, while you can express your height in feet, you wouldn't use square feet unless referring to a flat space.
