You can view and change your store currency from the Store defaults section of the General settings page. Before you change your store currency, review the impact and legal considerations this action has on your store.From your Shopify admin, go to Settings > General.
In the Store defaults section, under Currency display, click … and select Change store currency.
Select your new store currency from the list.

Review and update your product pricing. Because the value of different currencies is rarely equal, a product's value will likely be different in a new currency, which can impact your profit margins.
Review and adjust discounts to align with the new store currency.
Delete your existing shipping rates, then add the rates back in manually to display rates in the new currency.
Issue new gift cards to customers who have gift cards with remaining balances.
If you aren't using Shopify Payments, then update your markets when you change your store currency.
