Productivity Sauce

Google is not only a powerful engine, it also doubles as a rather versatile calculator. You can use Google search to perform simple calculations like 3+5 or 25*5/100, convert currencies and units as well as do other nifty tricks such as converting Arabic numerals to Roman (e.g., 2010 in roman numerals) and satisfying your curiosity (type, for example, mass of earth to find the mass of our planet).

If you happen to use the Google Chrome browser, you can put Google's calculating power at your fingertips by installing the Chromey Calculator extension. Once installed, the extension adds an icon to the Google Chrome main toolbar. Press it to bring up the calculator interface, type the desired calculations, hit Enter, and you should see the result in the main pane. But what happens if Google fails to return an answer? In this case, Chromey Calculator queries the WolframAlpha computational knowledge engine. Chromey Calculator keeps tracks of all queries, and it marks the source for each answer.
