How it works
Exchange rates are fetched from the Frankfurter API, which provides free access to rates published by the European Central Bank (ECB). The ECB publishes reference exchange rates for 30+ currencies against the euro every business day at approximately 16:00 CET. These are mid-market reference rates — not buy or sell rates — making them the standard benchmark used in commerce, accounting, and economic reporting.
When you convert between two non-euro currencies (e.g., USD to GBP), the tool uses the euro as an intermediary. It converts the source amount to euros using the source currency's EUR rate, then converts from euros to the target currency. This triangulation method is the standard approach and produces the same result as a direct rate. The math is: Amount × (Target Rate / Source Rate).
Historical charts are built by fetching time-series data from the Frankfurter API for the selected currency pair and date range. The data points are plotted on an interactive chart that lets you visualize trends, identify peaks and troughs, and understand the volatility of a currency pair over time. Available ranges span from 7 days to the full dataset going back to January 4, 1999 — the date the euro was introduced and the ECB began publishing daily rates.
