       | American football fields, or "soccer" fields? Surprisingly, the
       | answer is in the article:
       | 
       | > In some places, the earthquake extended the coastline by as
       | much as 250 meters, or about 820 feet, according to a statement
       | from the University of Tokyo. That's about the length of 2.2
       | American football fields.

         | In case anyone else was curious: The American football fields
         | are 109.8 meters long, while football/soccer fields are 90 to
         | 120 meters long (but most commonly 105 meters long for
         | professional stadium fields).

         | You can still say that the perimeter definitively got longer.
         | Just add a parameter epsilon greater than zero for each

         | some indefinite amount.

       | It's really strange how "football fields" or "Olympic swimming

       | headlines. Isn't the universality kind of the appeal of having
       | units of measurement? I'd argue most people see things that are a
       | meter long a lot more often than football fields.
