Drupal Commerce uses the internationally-recognized standard of CLDR data to provide multiple currency support. Currencies are formatted based on the locale of a language, giving a true localized experience. All of this is possible due to the underlying multilingual and localization capabilities of Drupal.
Visit the Commerce configuration page and go to the Currencies page in the Store section.
The currencies page shows a list of all currencies currently added. To add a currency, such as the Canadian Dollar, click on + Add currency. The next form will provide you with a list of available currencies to import. Select your currency and click Add
While not common, sometimes you may wish to modify a currency that was added. Once a currency is added, you can click Edit to modify the currency.
