A Euro is the official currency of 17 European countries, according to the European Central Bank. An important factor in converting currency is to know the exchange rate, which is the value of one currency compared to another. Based on the demand in national and international markets, currency exchange rates change daily. When traveling or investing in currencies, knowing how to convert Euros to U.S. dollars can be beneficial to you.
