I thought I would start a thread with a couple of useful tools from google, if you have some please share them. I commonly use google for addition of sorts, sure a calculator will do the same things but some of their features are pretty neat. For example if you want to find out how many bytes are in a 65 megabytes, you can simply type in:
bytes in 65 megabytes
and it will render the results, like this
http://www.google.com/search?hl=en&q...=Google+Search very handy for attachments. This can be used in any combination of bytes, kb, mb, gb, etc.
Here is a cheat sheet that shows some other cool examples but I am sure there are plenty more
