We always seem to want to convert various forms of measurements to some other various forms of measurements.  We used to have bookmarks for every conversion necessary: one for distance, one for weight, one for currency, and so on.  Then, Mango discovered Google Calculator.  Google has outdone itself and created the easiest conversion tool we've ever seen.  You simply write your conversion in plain English into the Google search box.  And with Firefox, the Google search box is just a CTRL+K away.

Examples follow.

You can convert distance, volume, currency, and even volume of data.

But, oh!  It gets better!  You can convert multiple units of measure at the same time!

And now, for the grand finale...

Google Calculator is cool.  Period.
