What is the value of one American dollar in Mexico?

The value of one American dollar in Mexico varies over time as it depends on the foreign exchange rate between the US dollar and the Mexican peso.

As of my last knowledge update in September 2021, the exchange rate was approximately 20 Mexican pesos per 1 US dollar. This means that one American dollar was worth 20 Mexican pesos at that time. Please note that exchange rates can fluctuate, so it's best to consult a reliable source for the most current exchange rate information.
