The British eventually used the Roman mile as a model in their measurement system, but they didn’t want to give up their furlong. The Roman mile was about seven-and-one-half furlongs, and when the British adopted it, they lengthened the Roman mile to eight furlongs, which equals 5,280 feet.
Moreover, How did 5280 feet became a mile?
In 1592, Parliament set about determining the length of the mile and decided that each one should be made up of eight furlongs. Since a furlong was 660 feet, we ended up with a 5,280-foot mile.

Furthermore, Who said a mile is 5280 feet?
The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in pre-modern England meant that the statute mile was made equivalent to 8 furlongs or 5,280 feet in 1593. This form of the mile then spread to the British-colonized nations some of which continue to employ the mile.

How did the measurement of a mile come about?
It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet. About the year 1500 the “old London” mile was defined as eight furlongs. At that time the furlong, measured by a larger northern (German) foot, was 625 feet, and thus the mile equaled 5,000 feet.
