Most Amazon Kindle books now have page numbers, which correspond to a particular print edition of the book. For example look at this Kindle book:
http://www.amazon.com/Programming-Py...9756477&sr=1-2
See where it says Length: 1632 pages? (darn, that is a long book!) Hover over that, and you will see the print edition the pages correspond to. If you have that print edition, you can refer to the page numbers on print and Kindle and they will match.
