Currency converter
Yen, dollars and the rest of a trip’s shopping list, converted at the rate the European Central Bank published today.
The amount you type stays in this page. The only thing sent anywhere is a request for the rate itself.
1What this rate is, and what it is not
The number here is the reference rate published by the European Central Bank — the mid-point between what banks are buying and selling a currency for. It is the honest starting point for a conversion and the number quoted in the news, but it is not a rate any shop, counter or card will give you.
What you are actually offered sits a little worse than this, because whoever changes the money makes their margin on the difference, and a card may add a separate foreign-transaction fee on top. Treat the figure here as the fair value of the money, then expect the quote you get to be short of it.
2Yen, in practice
Plenty of Japan still runs on cash: small restaurants, temple and shrine stalls, market stalls, older ticket machines. Having some yen before the first morning removes a class of small problems, and the rate you got for it is worth more attention than the rate you get at the airport on the way home.
The most useful thing this page does is let you price a purchase in your own money before you commit to it. A ¥3,000 bowl of ramen and a ¥30,000 knife feel very different once they are in the currency you are actually paid in — which is the whole reason guides here quote yen figures and let you do this conversion yourself.
3Where the rate comes from
The rate is fetched directly by your browser from frankfurter.dev, a public service that republishes the European Central Bank’s daily reference rates. The request carries nothing about you beyond what every web request carries, and this site sets no cookie and stores nothing: it never sees the request. The privacy policy names it as one of the services this site talks to.
Rates are published on working days, so a weekend or a bank holiday shows the last working day’s figure, with its date under the conversion. If the service cannot be reached from your browser, type the rate you were given instead — the arithmetic is the same, and it is often the more useful number anyway.
