Kwanzas are the official currency of Angola, but there are several synonyms used to refer to this form of currency. Some of the common synonyms include Angolan kwanza, Kz, and AOAs. These forms are often used interchangeably to denote the same currency. The Kwanzas have a standard monetary system that is used within the entire country. The value of the currency is determined by the government and is based on factors like inflation and exchange rates. Other forms of Angola currency include the centavo, which is a smaller denomination currency, and the Angolan escudo, which was used before the kwanza.
