How much is 1 peso worth?

Several countries use pesos as their currency and each one has a different conversion factor versus US dollars.

Exchange rates change every day so any answer posted here would be out of date almost immediately. While it's not normal WikiAnswers policy to say "use the internet", that's the best approach in this case. You can check a site such as www.xe.com, CNNMoney, etc. for the latest conversion factors.
