Google keep adding new features.
It seems like they are heading towards being some sort of typed-in command universal tool. Almost like the ultimate command line.
Now, prepare to toss away the silly GUI calculator on your computer. Google has a handy calculator built in. All you have to do is type you calculation into the Google search box, or search bar.
For example, try this 1+1 and see the result. Or have a look at calculator help.
Update: I just got lost in calculator help and tried a few things: try this out: 1000 litres in imperial teaspoons or 1024 ^ 3 in hex.
But when will C-Gate have this feature?
