A currency converter helps you translate money from one currency to another using official reference exchange rates. This calculator uses European Central Bank (ECB) daily reference rates, useful for estimating costs when planning travel, shopping, or cross-border budgeting.
How to use this calculator
- Enter the amount you want to convert.
- Select the currency you are converting from.
- Select the currency you are converting to.
- Use the swap button to reverse the direction if needed.
- Review the converted amount, exchange rate, reference rate date, and rate source.
Formula
Conversion uses cross rates through a common base currency. The amount in the source currency is converted to the base, then multiplied by the target currency rate. The displayed exchange rate shows how many units of the target currency equal one unit of the source currency.
Example
Converting $100 USD to EUR at a reference rate of 0.92 EUR per USD gives about €92. ECB reference rates are updated once per business day.
Frequently asked questions
How often do exchange rates change?
This calculator uses ECB reference rates updated once per business day, typically around 16:00 CET. Rates do not change on weekends or ECB holidays, so the reference date may be the most recent business day.
Is this the rate I will get at a bank or airport?
This calculator shows ECB reference rates for information and estimation. Banks, card networks, and exchange kiosks often add fees or spreads, so your actual rate may differ.
What if rates cannot be loaded?
If reference rates are unavailable, the calculator shows a friendly error message. Try again later when the exchange rate service is reachable.
