What is the measure of the value of one currency against another currency?

The measure of the value of one currency against another currency is referred to as the exchange rate. The exchange rate indicates how much of one currency you can obtain in exchange for another currency, essentially providing a means to compare the value of different currencies in global trade. It reflects factors such as economic stability, interest rates, and inflation between the two countries whose currencies are being compared.

In practice, exchange rates can fluctuate due to market forces, economic indicators, and geopolitical stability, making them a crucial concept in international finance and trade. Understanding exchange rates is essential for anyone involved in foreign exchange markets, international business, or traveling abroad, as it affects purchasing power and investment decisions.
