How many feet are in a mile?

A mile is defined as exactly 5,280 feet. This measurement is based on the imperial system used primarily in the United States and is derived from the Roman mile, which was originally defined as 1,000 paces (or about 5,000 Roman feet). Over time, the modern mile has been standardized to 5,280 feet due to various historical measurements and adjustments. Understanding this conversion is essential, especially in fields such as real estate, where precise measurements can impact property descriptions and conveyances.

The other options listed reflect incorrect conversions of a mile into feet, highlighting common misunderstandings about the mile's length. For example, 2,640 feet represents half a mile; 10,000 feet is more than a mile; and 4,320 feet is a three-quarter mile distance. Knowing the correct number of feet in a mile is fundamental for anyone involved in industries that require precise measurement of distance, such as surveying or land development.
