title_body: What is the definition for "location" in a kindle eBook?
upvoted_answer: According to the MobileRead Wiki, a location is 150 bytes.
  
  
    The Kindle uses an absolute position system named locations which are
    actually every 150 bytes in the file. Easy to generate accurately but
    are much smaller than a standard page so you get a range of numbers on
    every page. The exact formula is floor(bytes/150)+1, and note that
    this is bytes, not characters, and includes all the markup and tags in
    the mobi-html, not just the displayed text.
