Re: Announce: currency convertor
 

For those who'd like a quick way to convert currencies without installing an application

Point your browser to Google.com, fill in: <amount of source currency> <source, in ISO format> in <target, in ISO format>

e.g. 50 USD in EUR which converts 50 US Dollars to Euros.

Et voila...

Feature is documented here.

List of currencies with ISO format on Wikipedia.

Possible caveats: 1) need to be online (also at least one time necessary to get latest info about currencies) 2) Google stores your information (else, in case of program discussed in this thread's first post, Yahoo would do this). Both IMO diminishable.
