Rates come from the European Central Bank (ECB) and are updated every business day around 4:00 PM CET. The converter always shows the latest available rate.
How many currencies are supported?

Is the currency converter free?
Yes, the converter is completely free with no usage limits and no sign-up required. All calculations happen directly in your browser.
How do I read the historical chart?
The chart shows the exchange rate trend over the last 30 days. The X axis represents dates, the Y axis the rate. You can see if a currency strengthened or weakened over the period.
Can I use these rates for real transactions?
ECB rates are reference rates, not market rates. Banks and exchange services apply spreads and fees. Use this tool as a reference, but always verify the actual rate with your financial provider.
How does the automatic currency detection work?
The converter automatically detects your browser's time zone and selects the most likely local currency. For example, if you're in the UK it selects GBP, if you're in Japan it selects JPY. You can always change the currency manually.
What does the volatility indicator on the chart mean?
The volatility indicator shows how much the exchange rate has fluctuated over the selected period. “Stable” (under 1%) means minimal movement, “Moderate” (1-3%) indicates normal fluctuations, “High” (over 3%) signals significant movement. It's useful for deciding the best time to exchange currency.
