A total of 17.6 American football fields are in a mile. If that number of football fields were laid out end to end, they would occupy the linear distance of a mile.
A mile contains 5,280 feet. The standard length of the field used for playing American football is 100 yards, or 300 feet. Dividing 5,280 feet by 300 feet yields 17.6, the number of football fields in a mile. Canadian football is played on a field of a different size, which measures 110 yards, or 330 feet long. A mile could hold 16 Canadian football fields placed end to end.
