How many square feet is the US?

The total land area of the United States is approximately 3.8 million square miles. To convert this to square feet, you would multiply by 27,878,400 (the number of square feet in a square mile), resulting in approximately 106,269,120,000 square feet. This calculation assumes that the land area of the US is entirely contiguous, which is a simplification since the US also includes territories like Alaska and Hawaii.
