Currency Conversions

Currency

Currency conversion is the process of determining the equivalent value of one monetary unit in terms of another, based on the prevailing exchange rate between the two currencies. Exchange rates are determined in the foreign exchange market (Forex), the world's largest and most liquid financial market, with a daily trading volume exceeding $7.5 trillion USD as of 2022. Rates fluctuate continuously in response to macroeconomic indicators, central bank policy, geopolitical events, and market sentiment.

Two types of exchange rate systems govern how currencies relate to one another. Under a floating exchange rate system — used by the US Dollar, Euro, British Pound, and most major currencies — rates are determined by market supply and demand. Under a fixed or pegged exchange rate system, a government or central bank maintains a set exchange rate by intervening in currency markets. The Euro, introduced in 1999, represents a special case: a monetary union in which multiple sovereign nations share a single currency, eliminating exchange rate risk within the eurozone entirely.

For students of economics, finance, and international business, understanding exchange rates is foundational. Key concepts include purchasing power parity (PPP) — the theory that in the long run, exchange rates should equalise the price of identical goods across countries — and the carry trade, in which investors borrow in low-interest currencies to invest in high-interest ones. The exchange rates used on this page are sourced from the European Central Bank and updated daily, providing a reliable reference for academic and practical use.
