The eReaders have provided us with an interesting option, which for many goes unnoticed, but which many others value very much. I am talking about the function that, for example, the Kindle has show us the approximate time we have left to finish reading a book. This allows us, for example, to divide the end of a book into several days or moments in a precise way or not to stop reading at the precise moment, if we know that since we have little left to finish the book, we are going to stay half a event.
Now knowing the approximate time it will take us to read a complete book, in physical format, it is also possible thanks to the web howlongtoreadthis. And it is that this simple, but interesting web will tell us how much time we will spend reading almost any book. Its database has 12 million books, so you will almost certainly find what you are looking for.
The times that it shows us for all the books are for an average reader, and that has a reading speed of 300 words per minute. However, if you think that you cannot read the number of words per minute or that you even read some more every 60 seconds, it does not matter, since you will be able to quantify the words that you are able to read and the service itself will recalculate the time it will take for you to finish reading a certain book.
For example, we wanted to know how long it would take to finish The time between seams by MarÃa Dueñas, and according to this service we would use, if we read 300 words per minute, a total of 8 hours and 50 minutes.

I don't know what it will look like to you, but the truth is that that time is quite short for me, since this novel is not exactly short, but perhaps I will even read it again to know the precision that howlongtoreadthis offers us.
What do you think of this tool to know how much time we will spend reading a book?.
