Dictionary of Numbers is a neat Chrome extension that “translates” large numbers into terms that are easy to visualize. When you have the extension installed any time that you encounter a large number on the web you can highlight it and get a simple explanation of just how big that number is. For example, if you came across the number 238,900 you would quickly find out that that is the average distance in miles to the moon. The one minute video below shows you everything you need to know about the Dictionary of Numbers.
