Q: What is FX rate?

A: Definition of Exchange Rate. Exchange Rate (also known as forex rate, FX rate, foreign-exchange rate, or Agio ) is a relative value between two currencies at which one currency can be exchanged for another currency. It is also thought as the price of one currency in terms of another currency.

Q: How do you convert units to measurement?

A: Answers. To convert units within a measurement system, all you have to do is multiply or divide, depending on the units you are converting.
