How it works
Pick an amount and two currencies to convert at the mid-market (interbank) reference rate. Rates are seeded from European Central Bank data and refreshed daily; the calculation runs entirely in your browser. The result updates as you type and nothing leaves your device.
The converter computes a cross rate from base-USD reference values: the rate from currency A to currency B is the USD rate of B divided by the USD rate of A. See our methodology for sources and limits, or browse all currency pairs.
Frequently asked questions
Is the currency converter free?
Yes — it runs entirely in your browser, with no sign-up and no data sent to a server.
How accurate is the currency converter?
It uses mid-market reference rates derived from European Central Bank data (as of 2026-06-13). These are wholesale midpoints; the rate a bank or transfer service gives you will be slightly worse.
