Watch the video above for the basics of exchange rates.
An exchange rate is the value at which one currency can be exchanged for another.
The exchange rate is represented as a ratio of the two currencies. It tells you how much of the top currency you can get for one unit of the bottom currency.
For example, if the exchange rate between the Euro and the US Dollar is 0.81, that means 1 US Dollar equals 0.81 Euros.
