About the Currency Converter

The rates here are the European Central Bank's daily reference rates, published once each working day. They are the closest thing there is to a neutral answer to "what is this worth", which is why news reports and accounting systems quote them.

What they are not is what you will get. A bank, a card or a transfer service gives you a slightly worse rate than the reference, and that margin is how they are paid for the transaction. Treat the figure here as what a fair rate looks like, so you can judge whether a quoted rate is reasonable — not as a prediction of what will land in your account.

The rate table is downloaded once when the page opens, through this site rather than directly from the source. Your browser never contacts a third party, and the conversion itself happens here, which means the amount you type is never transmitted anywhere. For a tool people use to work out salaries, invoices and transfers, that is worth stating plainly.

Around thirty currencies are covered — the ones the ECB publishes, which includes everything commonly needed: the dollar, euro, pound, rupee, yen and the major Asian, European and American currencies. It does not include every currency in the world, and it does not cover cryptocurrencies, which have no official reference rate.

If the rates cannot be fetched, the tool says so and refuses to convert rather than falling back on a stale or invented number. A currency converter that quietly guesses is worse than one that admits it does not know.

How to use the Currency Converter

  1. Enter the amount

    The conversion updates as you type. Nothing you enter is sent anywhere.

  2. Choose the currencies

    Listed by code and full name, so there is no confusion between the several currencies called a dollar.

  3. Check the rate

    The rate for a single unit is shown alongside, which is the number worth remembering.

  4. Compare it with what you are offered

    Your bank or transfer service will quote slightly worse. How much worse is the fee you are actually paying.

Frequently asked questions

Where do these rates come from?
The European Central Bank's daily reference rates, published once each working day. They are the standard neutral reference — the rates quoted in news reports and used by accounting systems — rather than any one bank's pricing.
Why is my bank's rate different?
Because the reference rate is the mid-market rate, and a bank, card or transfer service takes a margin on it. That margin is how they are paid. Comparing their quote against the figure here tells you what the transaction is actually costing you.
How often do the rates update?
The European Central Bank publishes once each working day, so the rates do not move over a weekend or a holiday. The publication date is shown beneath the converter rather than left to be assumed.
Is my amount sent to a server?
No. Only the rate table is fetched, once, when the page opens. The conversion happens in your browser, so the amount you type — a salary, an invoice, a transfer — is never transmitted.
Are cryptocurrencies included?
No. They have no official reference rate, their prices differ between exchanges and move by the second, so a daily figure would be misleading rather than useful.
What happens if the rates cannot be fetched?
The tool says so and stops, rather than converting with a stale or invented rate. A wrong exchange rate presented confidently is worse than no answer at all.
