This is pretty neat. I've used the Google Omnibox to do calculations and conversions but never knew you can also do it right in the Chromebook app launcher.
You don't even have to open a browser tab. Just type in the conversion or calculation and the answer will show up right above the suggested searches.
Another great feature of Chromebooks for students and teachers.
