European Central Bank

Euro exchange rates, convert currency and key interest rates

The European Central Bank provides official euro reference rates and informational currency conversions using the latest preceding published rates when needed, plus current key interest rates and optionally earlier changes.

Convert currency

Convert an amount between currencies using the ECB euro reference rates, including euro and cross-currency conversions. Dates without a published rate use the latest preceding rate; only currencies with an ECB rate on that date are available. Reference rates are informational, not transaction rates.
