The latest blended exchange rate for one currency pair: units of the quote currency per 1 unit of the base, with the date and the central banks behind the rate. Rates update once a day. Multiply an amount by the rate to convert it. Blended from central-bank reference rates, not an official central-bank rate. Frankfurter data served by Eden Engine; not an official Frankfurter product.
