Understanding Currency Conversion

Currency conversion converts amounts between different currencies using exchange rates. Rates fluctuate and represent relative value between currencies. Financial calculations require careful handling of floating-point precision.

Details
What is the "mid-market rate" and how does it differ from what my bank charges?expand_more
The mid-market rate is the midpoint between the global bid (buy) and ask (sell) prices on the interbank currency market. Your bank or payment service adds a markup (spread) to this rate — typically 0.5-2% for credit cards, 1-3% for bank wire transfers, and 3-7% for airport kiosks. Services like Wise and Revolut use near-mid-market rates with transparent fixed fees.
How often are the exchange rates updated?expand_more
Rates are fetched when the page loads from the European Central Bank's daily reference feed, which publishes updated rates each business day at approximately 16:00 CET. Currency markets trade continuously 24 hours a day, 5 days a week, and rates can fluctuate between ECB publications. The timestamp displayed at the top shows exactly when the current rates were last published.
Why do some currencies show very large or very small numbers?expand_more
This is due to differences in unit value between currencies. The Japanese Yen (JPY) and South Korean Won (KRW) have small base units — 1 USD is approximately 150 JPY. The Kuwaiti Dinar (KWD) is a high-value currency where 1 KWD equals approximately 3.25 USD. These differences reflect each country's historical monetary policy choices, not economic strength.
Can I use this tool offline?expand_more
The exchange rate data is cached after the first successful fetch, so the converter continues to work if you lose connectivity, showing the last known rates. However, rates will not update without a network connection. The page displays a prominent warning when cached rates are being used.
How should I handle currency conversion in a multi-currency e-commerce system?expand_more
For e-commerce, use a server-side API like Open Exchange Rates to fetch daily rates and store them in your database. Apply a consistent markup policy and display the converted price at product-page load time. Lock the exchange rate at checkout to prevent rate fluctuations between cart and payment. This web-based converter is useful for estimating prices during development but should not drive production pricing logic.
