Where can I find on-line, linkable currency converters?

Joe Sam Shirah

There are many sites like Canada's Royal Bank that convert only to local currencies ( US and Canadian dollars ), and others like the domino.kappa.ro, that uses the rates of the National Bank of Romania and converts 20 or so currencies in either direction. However, the most complete and popular sites are OANDA, The Currency Site, and xe.com The Full Universal Currency Converter which, as of this date, convert between 164 and 180 currencies respectively.

Be sure to check the sites' documentation for limitations and restrictions.
