Google Calculator and Suggestions

(Woo, Trebuchet is my favorite font. == happy with new dashboard)
So, I just noticed today that if you have Google suggestions turned on, like in my search bar in Firefox, you can do the calculator stuff, and it will pop up as the first suggestion. I use Google for a calculator, spell checker, and thesaurus all the time, this just makes my life two buttons easier/faster.
If you're not familiar with the calculator stuff, check this out. You can type stuff like "1440 minutes in hours", and the conversion (=24 hours) will show up as the first suggestion.
