Mexico is the country slightly less than three times the size of Texas that uses the peso as its currency.
Mexico covers about 1.96 million square kilometres, while Texas covers roughly 696,000 square kilometres. That makes Mexico approximately 2.8 times larger than Texas, close to—but below—the three-times comparison in the question. Mexico occupies the southern part of North America and borders the United States, Guatemala, and Belize.
Mexico's official currency is the Mexican peso, with the currency code MXN and the symbol $. The peso is divided into 100 centavos. Because several countries use currencies called pesos, the country name or currency code is important when distinguishing the Mexican peso from the Philippine, Dominican, or Uruguayan peso.
Mexico's modern peso traces its name and monetary history to the Spanish colonial peso. The current peso was introduced in 1993 after a major currency redenomination, when 1,000 old pesos became 1 nuevo peso; the word “nuevo” was later dropped from everyday currency naming.
