How to Convert Currencies: Exchange Rates and Currencies

Learn how to convert currencies and understand exchange rates between the world's main currencies.

Converting currencies is a common operation when travelling, shopping online or doing international business. In this guide we explain how exchange rates work and how to use a converter.

1 Understand the exchange rate

The exchange rate is the relationship between two currencies: how many units of one currency you need to get one of the other. For example, if 1 EUR = 1.09 USD, one euro is worth 1.09 dollars.
