What are some good currency exchange rate websites?

XE is a website that facilitates currency exchange and has a currency converter tool that includes live rates of the value of currency. Yahoo! Finance also offers a currency converter, available at Finance.yahoo.com under the tab Currency Converter.

While currency conversion tools are useful, anyone who wants to exchange currency at a bank or currency exchange service is not likely to receive the exact value of the exchanged currency because these institutions charge a transaction fee and may establish their own conversion rates. Using an online currency converter to check the up-to-the-minute value of foreign exchange rates can help determine which currency exchange service offers the best rates.
