A currency converter multiplies an amount in one currency by the exchange rate to a second currency. Each currency is identified by its three-letter ISO 4217 code — USD for the US dollar, EUR for the euro, GBP for the British pound, JPY for the Japanese yen — so there is never ambiguity between similarly named currencies. The rates this tool uses are mid-market reference rates published each business day by the European Central Bank, the midpoint between the buy and sell prices in the wholesale market.

We fetch the rate on our server to avoid browser CORS limits, then return the rate, the converted result and the date it was published so you can see exactly how current the figure is. Foreign-exchange markets move continuously, so a live trading quote may differ slightly from the daily reference rate, and the rate a bank or card actually gives you is lower still: providers add a margin on top of the mid-market rate plus any fixed fee. Treat the result as an accurate baseline for comparison rather than the exact amount you will receive in a transaction.

The swap button flips the two currencies in one click so you can convert in the opposite direction without re-selecting.
