What is the currency used in Saudi Arabia?

The currency used in Saudi Arabia is the Saudi Riyal. It is the official currency of the kingdom and is denoted by the symbol "SR" or sometimes "ريال" in Arabic. The Saudi Riyal is subdivided into 100 halalas. This currency has a long history in the country and is a crucial part of the economy, used for both domestic trade and international transactions.

Other currencies listed, such as the dinar, dollar, and euro, are used in different countries and regions but do not represent the monetary system of Saudi Arabia. The dinar is used in several other countries in the Middle East, the dollar primarily refers to the US dollar or others like the Australian dollar, and the euro is used by European Union member states. Thus, while they are significant currencies globally, they are not applicable within the context of Saudi Arabia's economy.
