Convert between world currencies using daily European Central Bank rates. Useful for invoicing, travel, and international pricing.
Rates are updated daily via the European Central Bank and are for reference only. For financial transactions, payments, or invoicing, always confirm the rate with your bank or payment provider.
At its core, a currency conversion is simple arithmetic: you multiply an amount by a ratio that expresses how much one currency is worth in terms of another. If 1 Euro buys 1.08 US Dollars, then 100 Euros buys 108 Dollars. That ratio is the exchange rate, and everything else is just plumbing.
What makes it complicated in practice is where that ratio comes from. The rate shown here is the ECB reference rate, published daily by the European Central Bank. It reflects the midpoint of trading activity across global currency markets and is the closest thing to a neutral, official rate. It is not the rate your bank charges. Banks, card providers, and transfer services all add a margin on top, typically somewhere between 0.5% and 3%, which is how they make money on conversions.
Rates move continuously during market hours because currencies are traded around the clock across global markets. The ECB fixes its reference rate once per business day at around 16:00 CET, which is why this tool updates daily rather than in real time. For most reference purposes like checking an invoice, understanding a price, or planning a trip, a daily rate is more than precise enough.
