Which currency was introduced in Argentina in 1992 to replace the austral?

The Argentine peso was introduced in 1992 to replace the austral.

Argentina established the peso through the Convertibility Plan, which took effect on 1 January 1992. The reform defined the new peso at a fixed rate of one peso to one U.S. dollar under the original convertibility arrangement. It also removed four zeros from the previous currency: 10,000 australes became one peso.

The Central Bank of the Argentine Republic issues the currency. The Argentine peso is divided into 100 centavos and has the ISO 4217 code ARS. The fixed one-to-one arrangement ended in 2002 after a severe economic and financial crisis.

Argentina has used the name peso at different times in its history, so dates matter when identifying the currency. The modern peso is not the same unit as earlier Argentine pesos or the austral that preceded it.
