"Google it!" may have entered our lexicon as a way of saying, "look it up", but the search-engine giant has a few more tricks up its sleeve that you can use:
To use Google as a dictionary, type 'define: word' in the search box. Google will return a comprehensive dictionary entry, including definitions, pronunciation, statistics on use over time, word origin and a tool that you can use to translate the searched word into another language.
Speaking of translating, just type 'translate ABC into language' to get a quick translation of a word or phrase. You can use this feature to translate text in an unfamiliar language into English, too.
To use Google as a calculator, type 'calculator' into the search box or just type your problem into the search box, followed by the equal sign. Press enter/return and the calculator will appear on the screen with your answer already displaying. You can use common arithmetic symbols such as '+', '-', '*' (multiply) and '/' (divide) as well as typing in more complex queries (i.e. 'square root of x=') to get a result.
Google Chrome users can use their computer's microphones to voice search. Just click the microphone icon in the search box and speak your search term.
Quickly find out the weather in a given location. Just type 'weather' into the search box to see what it's like outside where you are at that moment (Google will use your computer's IP address to estimate your location), or type 'weather' followed by a place to find out if it's better than here.
Perform quick unit conversions (including money at current exchange rates) by typing in something along the lines of '28 degrees F in C' or '100 dollars to euros'. Google will return your answer and a calculator.
