CurrencyR is a package for converting currencies into other currencies. It is backed by the Fixer.io API, a free JSON API for current and historical foreign exchange rates published by the European Central Bank.
You need a Fixer API key for this to work! Please go to http://fixer.io and sign up for a free API key. Then add export FIXER_KEY=apikeygoeshere to your ~/.bash_profile to use this service.
