Currency Conversion Calculator: Illustrative Exchange Rates
Currency exchange rates move continuously in global markets, so any rate shown on a static calculator is inherently out of date within hours. This calculator provides illustrative reference rates to demonstrate the mechanics of currency conversion and give a rough sense of relative values. It is not suitable for pricing financial transactions, contracts, or purchases where the exact rate matters. To convert a specific amount, select your source currency and target currency and enter the amount. The calculator shows the converted value, the exchange rate in both directions, and the reverse rate. Below the calculator, a reference table lists all 20 currencies with their approximate value in US dollars. All rates are stored as USD equivalents so any pair can be calculated by cross-multiplying through USD. For current rates, use the Federal Reserve H.10 Foreign Exchange Rates release (linked below), which publishes official daily noon buying rates, or contact your bank or currency service provider for the rate applicable to your specific transaction.
Formulas
All rates stored as: 1 unit of currency = X USD
Converted amount = input_amount × rate[from] / rate[to]
Exchange rate (from to to) = rate[from] / rate[to]
Reverse rate (to to from) = rate[to] / rate[from]

These rates are approximate values for reference only. For official daily rates, see the Federal Reserve H.10 release.

Frequently asked questions
Why do exchange rates constantly change?
Exchange rates are determined by supply and demand in global foreign exchange (forex) markets, which operate 24 hours a day, five days a week. Factors affecting rates include interest rate differentials between countries, inflation rates, economic data releases, political events, and central bank interventions. The US dollar strengthens when US interest rates rise relative to other countries.
What is the difference between the mid-market rate and the rate my bank gives me?
The mid-market rate (also called the interbank rate) is the midpoint between the buy and sell rates in wholesale forex markets. Banks and money transfer services add a spread (markup) on top of this rate to earn revenue. Consumer exchange rates from banks can be 2% to 5% worse than the mid-market rate. Wire transfers and specialist currency services often offer better rates than physical currency exchanges.
What does the Federal Reserve H.10 release show?
The Federal Reserve publishes the H.10 Foreign Exchange Rates release, which shows daily noon buying rates for major currencies against the US dollar as collected from selected banks. These are close to mid-market rates and are official US government data. For consumer transactions, your actual rate will differ.
What is a floating vs pegged exchange rate?
A floating exchange rate is determined by market forces. Most major currencies (USD, EUR, GBP, JPY) float freely. A pegged (or fixed) exchange rate is set by a government or central bank at a specific level against another currency. For example, the Hong Kong dollar is pegged to the US dollar within a narrow band. The UAE dirham has been pegged to the USD since 1997.
What is currency risk?
Currency risk (also called exchange rate risk) is the potential for financial loss due to changes in exchange rates. It affects international travelers, importers, exporters, and investors holding foreign assets. A US investor holding European stocks, for example, can lose money in dollar terms if the euro weakens even if the stocks gain value in euros.
