What does the exchange rate signify?

The exchange rate signifies the price of one currency in relation to another, which is essential in understanding how currencies trade in the global market. When you look at exchange rates, they tell you how much of one currency you need to spend to acquire a unit of another currency. For instance, if the exchange rate between the US dollar and the Euro is 1.2, it means that 1 US dollar can be exchanged for 1.2 Euros. This measure is crucial for international trade, travel, and investment because it directly affects the purchasing power across different currencies and helps businesses and individuals make informed financial decisions regarding foreign transactions.
