Forex exchange rate is the value of two currencies relative to each other. This relationship is usually expressed as the amount of one currency required to buy a unit of another currency.

For instance, if on a particular day one US dollar can buy 110 Japanese yens then the foreign exchange rate for the two currencies would be 1:110. This equation is also known as pairing. The pairing can be reversed to indicate how many US dollars a single unit of Japanese yen can buy.
