How many square feet are in an acre?

An acre is a unit of area commonly used in the United States to measure large plots of land. One acre is equal to 43,560 square feet. This is derived from the fact that an acre was historically defined as the amount of land that a team of oxen could plow in one day. The exact size of an acre can vary slightly depending on the shape of the plot of land, but it is typically very close to 43,560 square feet. This conversion is important for those involved in real estate, farming, or land management, as it allows them to accurately measure and price land based on its area in square feet or acres.
