One can always simply go to google and you’ll have access to the standard currency converter except it’s limited to Bitcoin. What about Litecoin or Peercoin to name a few? You can navigate to the websites that list their values but I like to keep things streamlined and simple and while searching around I found preev.com. Clean simple, responsive and does the job.

The pulldown buttons give you access to other currency types which is super handy.
I love this site alot, it’s in my bookmarks.
