Google’s ultra sparse home page is just one of the things that helped the search giant set itself apart. But it also hides the fact that there’s so much more you can do with Google. For example, you can use Google as a free proxy by entering cache:website.com to view a web page that’s been blocked from the computer you’re using. Google also has a built-in converter calculator for metrics, bytes and more. You can enter quarter cup in teaspoons, seconds in a year, 5 US dollars in Euros and countless others. Check it out.
