PrestaShop can accept a large number of currencies. By default, there is only one standard currency: the one for your country. However, you must add and configure new currencies depending on your customers' needs. Indeed, customers will appreciate the ability to display your shop's prices in their country's currency.

The two sections at the bottom of the "Currencies" page are very simple yet essential, as relate to your currencies exchange rates (or "conversion rates"). To quote Wikipedia, "In finance, an exchange rate between two currencies is the rate at which one currency will be exchanged for another. It is also regarded as the value of one country’s currency in terms of another currency." Rates change daily, sometimes drastically depending on current events, and your shop should always be updated to the latest values.

In order to change the default currency, you must go to the "Localization" page of the "Localization" menu, and use the "Default currency" option from the "Configuration" section.
If the currency you want to use is not available in this option, you must import the currency from one of the countries which use it, using the "Import a localization pack" section of the "Localization" page.

Updating the Currency Rates

In PrestaShop, there are two ways to update your conversion rates:

Note that the rates are provided as-is: the PrestaShop team does pay attention to have correct rates in these file, but might slightly differ from the actual ones, if only because these rates can fluctuate greatly in a short time.

Adding a New Currency

The easiest way to add a country's currency is to import its localization package. This is done in the "Localization" page, under the "Localization" menu. Once import, you must go the "Currencies" page to enable it.

You might need to add a currency not featured in any the localization packages. In that case, you can use the creation form.
