It is the value of a foreign nation’s currency in terms of the home nation’s currency. For example an exchange rate of 7 South African Rand (ZAR, R) to the United States dollar (USD, $) means that ZAR 7 is worth the same as one USD . The foreign exchange market is one of the largest markets in the world. By some estimates, about 3.2 trillion USD worth of currency changes hands every day.
