Type an amount, pick two currencies and read a rounded answer at the European Central Bank (ECB) euro foreign exchange reference rates. Below the result, a cheat sheet lists typical amounts in both directions, from about €1 to about €500.
The amount accepts a dot or a comma as the decimal mark (“2,5”) and ignores spaces. A separator followed by exactly three digits groups thousands, so “1,000” is one thousand; “1.234,56” and “1,000.50” also work. Negative amounts are rejected. The amount and currencies are kept in the address (?a=75&from=CZK&to=EUR) for bookmarks and sharing; nothing is stored in the browser. The rate date is always shown, with a note when the rates are more than 14 days old. Copy gives a line such as “¥1,200 ≈ €6.84 (ECB rate of 23 Oct 2026)”.
Example
Suppose €1 = 25 CZK. This rate is invented; the page shows the real one.
- 75 CZK → ≈ €3.00. Results under 10 get two decimals.
- €12.50 → ≈ CZK 313. The exact value is 312.5; from 100 up, results are whole numbers.
With €1 = 160 JPY, 1,250 yen is 7.8125 euros, shown as ≈ €7.81. The rate lines under the result give both directions to three significant figures. For a weak currency they use 100 or 1,000 units, for example “¥100 ≈ €0.625”.
Limitations
- These are reference (mid-market) rates, not what a bank, card or exchange desk charges.
- They are not live. This page refreshes its copy weekly, on Saturday morning UTC, so during the week the rate date can be several days old.
- No historical rates and no charts.
- Only 17 currencies are offered: EUR, GBP, CHF, CZK, PLN, HUF, RON, DKK, SEK, NOK, ISK, TRY, USD, CAD, CNY, JPY and KRW.
- The page needs a connection to load the rates; it does not work offline.
The only request is for the public rates file from data.toolbit.co. Your amount never leaves the browser.
FAQ
Where do the rates come from?
From the ECB’s euro foreign exchange reference rates. They come from a daily consultation among central banks, usually around 14:10 CET, and are published around 16:00 CET on each working day, except TARGET closing days. The ECB states they are for information only and that using them for transactions is strongly discouraged.
Why does my bank or card show a different amount?
A bank or card network uses its own rate, usually with a margin or fee, at a different moment. A reference rate is one daily figure without costs.
When do the rates update?
The ECB updates on working days. This page copies the rates once a week, on Saturday morning UTC, after Friday’s publication, and shows the date of the rate it uses.
How is the result rounded?
Under 10, two decimals; from 10 to under 100, one; from 100 up, whole numbers. A currency never gets more decimals than it uses: ISO 4217 lists no minor unit for the yen, the won and the Icelandic króna, so they are always whole. Rounding is half up, and the size is checked again afterwards, so 9.995 becomes 10.0.
