Currency Converter
Convert between 30+ world currencies using daily European Central Bank reference rates.
About this tool
Convert an amount between more than thirty world currencies — USD, EUR, GBP, BDT-adjacent majors, JPY, AUD, and more — using daily reference rates from the European Central Bank via the free Frankfurter API. The rate and its date are shown with every result.
Reference rates are mid-market rates: the midpoint between buy and sell. Banks and payment services add a spread on top, so treat results as the fair-market baseline your provider's rate should be compared against.
Common uses
- Estimate what a freelance invoice converts to in your currency
- Compare a bank's exchange rate against the mid-market rate
- Budget travel expenses in your home currency
Frequently asked questions
How current are the exchange rates?
Rates are European Central Bank daily reference rates, updated around 16:00 CET on working days. The rate date is displayed with each conversion. This tool requires an internet connection to fetch rates.
Why does my bank give a worse rate than shown here?
These are mid-market rates with no margin. Banks, cards, and transfer services add a spread (typically 0.5–4%) plus fees — that difference is their revenue.
