About exchange rates

An exchange rate states how much of one currency you get for one unit of another. A rate of 1 GBP = 1.16 EUR means one pound buys 1.16 euros.

The ECB publishes reference rates once per banking day. They serve as a benchmark for contracts and accounting, but the price you pay in a shop or bank always includes a markup.

Conversion between two non-euro currencies goes through the euro as an intermediate step, known as a cross rate.

Rates are European Central Bank reference rates, fetched via Frankfurter, updated every banking day around 4pm CET. Banks and exchange bureaus add a margin, so the price you get is somewhat worse.
