I know that 1 USD=12 Peso (or something around that). So does that mean that 12 peso are 12 pesos? Because the websites I was looking at only used the word peso in singular form. In other words if you exchange 1 USD for 12 peso, you can spend those pesos independently, right? Like you can pull five pesos from that 12, and it leaves you with 7? ---

I… I don’t understand your question. 😕 1 USD is approximately 12 mexican pesos using the current exchange rate. In English (and I believe in Spanish) the plural of “peso” is “pesos”, so the website you used had a grammatical error. I am not sure what the rest of your question means. I suppose if you are asking if “12 peso” is a different currency from “Mexican pesos”, then the answer is almost certainly, no, it is not. ---

In both Spanish and English, the plural of “peso” is “pesos.” If you show up at the airport and the dollar purchase price is MX$12.00, you’ll be given 12 pesos. That may be a 10 peso coin plus a two peso coin, or any mix and match thereof. If you use the 10 peso coin to buy a bottle of water that costs 5.50 pesos, you’ll be given 4.50 pesos as change. ---
