About converting US dollar to Euro
The ECB publishes how many dollars one euro buys. To go the other way, the converter divides 1 by that rate, so 1 US dollar = 1 ÷ (dollars per euro) euros. The working box under the result shows the sum.
If you are travelling in the euro area, paying in euros with a card that charges no foreign transaction fee is usually cheaper than changing cash at an airport counter.
Banks and exchange companies add a margin to the mid-market rate shown here, and some charge a fixed fee as well. Compare the final amount received, not just the headline rate.
How the USD to EUR rate is worked out
Rates are stored per euro, so every pair is a cross rate through the euro, and the inverse is 1 divided by the rate. Major currencies use the European Central Bank’s euro reference rates; others, such as the Pakistani rupee and Gulf currencies, use the open-source currency-api feed, linked through the US dollar. The working box under the result shows the sum with today’s numbers.
The rate is a mid-market reference for information only. For a transfer, compare the amount the recipient receives with two or three providers. For any other pair, use the full currency converter.
