The term "Peso" refers to the currency used in several countries, primarily in Latin America. It is derived from the Spanish word for "weight" and has been in use since the colonial era. Countries like Mexico, Argentina, and Chile have their own versions of the peso, each with distinct values and symbols. The peso is subdivided into smaller units, typically cents, and is used for everyday transactions, including buying goods and services. The value of the peso can fluctuate based on economic conditions, inflation, and exchange rates, making it important for travelers and businesses to stay informed about its current worth.
