Exchange Rate
The price at which one currency can be exchanged for another currency.
Full Explanation
An exchange rate is the value of one currency in terms of another. For example, if 1 USD = 80 INR, that is the exchange rate between US Dollar and Indian Rupee. Exchange rates are constantly changing based on market forces. They can be fixed (government-set) or floating (market-determined). The exchange rate determines how much foreign currency you receive for your home currency in a transaction.
