Currency Converters

A currency converter is only as good as its rate, so these pages are strict about one thing: no rate is written into a page. The rate is fetched by your browser when the page opens, and the result always states where it came from, which date or time it applies to and when it was fetched. If the request fails, you see a message, not a stale number.

Money. The currency converter covers the euro and the 29 currencies for which the European Central Bank publishes a daily reference rate.

Dedicated pages exist for the most common pairs: euro to dollar, pounds to dollars, yen to dollar and pesos to dollars.

The ECB sets these rates once per working day at around 16:00 Central European Time and publishes them for information. They are a fair picture of what a currency is worth, not the rate a bank, card or exchange office will give you.

Crypto. The Bitcoin and Ether converters use the current price reported by CoinGecko, an average across exchanges, in US dollars, euros or pounds.

What is sent where. The fiat converters request the full ECB rate table from api.frankfurter.dev; the request is identical for every visitor and reveals neither your amount nor your currencies.

The crypto converters ask api.coingecko.com for the price of one coin. In both cases the amount you type stays in your browser.

These pages are for orientation: budgeting a trip, checking an invoice, getting a sense of scale. They are not financial advice, and they are not a quote for a transaction.
