Currency Converter

A currency converter translates an amount of money from one currency into another using an exchange rate — the price of one currency expressed in terms of another. Exchange rates exist because countries use different currencies, and global trade, travel and investment constantly require swapping one for another.

Exchange rates are set by the foreign exchange (forex) market, the largest and most liquid financial market in the world, trading trillions of dollars a day. Rates fluctuate continuously based on interest rates, inflation, economic data, political events and market sentiment. The rate you see quoted — sometimes called the "mid-market" or "interbank" rate — is the midpoint between what buyers and sellers are offering, and it's the fairest reference point for a conversion.

In practice, the rate you actually get when exchanging money is usually worse than the mid-market rate. Banks, airport kiosks and many apps add a margin or markup, and may charge an additional fee. That spread is how they profit. The difference can be small for major currency pairs but significant for exotic ones or at tourist-facing exchange counters, so it pays to compare providers and look for ones that exchange at or near the mid-market rate.

Currency pairs are quoted in a standard way — for example, EUR/USD at 1.08 means one euro buys 1.08 US dollars. Major pairs involve the world's most-traded currencies (USD, EUR, GBP, JPY), while pairs involving smaller economies tend to have wider spreads and more volatility.

For everyday needs — estimating a hotel price abroad, checking the cost of an international purchase, or budgeting for a trip — a converter using recent rates is perfectly adequate. For larger transfers, where even a small percentage matters, use a service that shows the live mid-market rate and discloses its fees clearly. Because rates change by the second, any converter result is a snapshot for reference, not a guaranteed quote.
