Currency Gadget is free and safe and lets you convert between several currencies from your desktop and on-line. The gadget works fine (Exchange Rates stopped working a few days ago), but if you need to use always a particular pair of currencies, it won’t remember your selection across Windows sessions defaulting to USD / Euro.
The gadget is able to convert between Albanian Lek, Algerian Dinar, Argentine Peso, Aruba Florin, Australian Dollar, Bahamian Dollar, Bahraini Dinar, Bangladesh Taka, Barbados Dollar, Belarus Ruble, Belize Dollar, Bermuda Dollar, Bhutan Ngultrum, Bolivian Boliviano, Botswana Pula, Brazilian Real, British Pound, Brunei Dollar, Bulgarian Lev, Burundi Franc, Cambodia Riel, Canadian Dollar, Cape Verde Escudo, Cayman Islands Dollar, CFA Franc (BCEAO), CFA Franc (BEAC), Chilean Peso, Chinese Yuan, Colombian Peso, Comoros Franc, Costa Rica Colon, Croatian Kuna, Cuban Peso, Czech Koruna, Danish Krone, Djibouti Franc, Dominican Peso, East Caribbean Dollar, Egyptian Pound, El Salvador Colon, Estonian Kroon, Ethiopian Birr,
