GoogleCalc

I have just released GoogleCalc. Provide it with any calculation or conversion and within seconds you will have an answer (if Google can find it).

I like to put this executable in a folder in My Documents then map said folder to my Path environment variable (right-click My Computer, Properties, Advanced tab, Environment Variables, under "User variables for " hit New, enter "path" for the name and the path to your GoogleCalc directory as value. Now you can enter the name of the app in the Run dialog or command line.
