Why 5,280 is special

5280 is the least memorable-looking number in everyday measurement, and that is exactly what makes it interesting: a statute mile is 1760 yards, and because a yard is three feet, the mile works out to 5280 feet rather than any round figure. It stands in direct contrast to the metric kilometre's clean 1000 metres.
