I recently discoved the Google Calculator, and since then I've not had any need for the Calc
application in Windows or OSX.
The thing is that you can google for a mathematical
expression, e.g. 3 + 9. More advanced
expressions, using functions such as square root, sine etc. is of course also
What's really cool is that the calculator can work with units. For example 50 meters / 3 seconds gives the
result in meters per second. 60 watt
* 24 hours gives the result in joules.
It's also possible to convert units, e.g. 3 km in miles or more advanced
conversion such as 60 watt
* 24 hours in calories.
Pretty cool, isn't it?
