A mile is a unit of linear measure equal to 1,760 yards, while a foot is a unit of length in the Imperial units and U.S. customary units.

Miles are abbreviated as mi while a foot is abbreviated as ft.

**Formula to convert miles to feet.**

To convert mi to ft, we use the conversion ratio that we get from how they relate.

We are told that 1 mile is equivalent to 5280 feet.

Therefore, to convert mi to ft we multiply the miles by 5280.

**Length in ft = Length in mi x 5280**

**Example:**

Convert 400 miles to feet.

**= 400 x 5280**

**= 2,112,000** **feet.**
