EUR to CZK Converter
Euros to Czech koruna is one of the rates the European Central Bank prints directly, so this page does no cross arithmetic at all: the ECB publishes koruna per euro, and that is the number in the Rate cell. The page opens with EUR in the From box and CZK in the To box, ahead of whatever the converter last remembered, and the readout says "EUR to CZK uses the published euro rate directly" so you can tell it apart from a pair like koruna to dollars, which we calculate from two published rates and label as ours. The publication date is printed in the chip above the panel, in the Rates from cell under the form, and in the block the Copy button writes to your clipboard, because a rate without its date is only half a figure. There is no separate page for the other direction: the Swap button in the row under the panel reverses the pair in place and makes this a Czech koruna to euro converter at the same dated set. Everything happens in your browser once the rates arrive from this site's own route, so what you are converting is never sent to us or to the ECB. And the limit is stated where you can see it: the ECB publishes reference rates once a working day for statistical use, with no fee, no spread and no card markup, so a bank, a card or a transfer service in Prague will settle at its own, different number.
Loading the published reference rates.
The rates in the panel are the euro reference rates the European Central Bank published on the date shown. The server that answered this page keeps its own copy of that file, asked for at most once every twelve hours and handed unchanged to everyone that server answers, and the amount you type is converted in your own browser: it is never sent anywhere. The date beside the answer is the one you are actually looking at. The ECB publishes on working days only, so a Saturday or a public holiday shows the previous working day's set rather than a new one.
Dated, and published once a day. Arithmetic at the European Central Bank reference rate for the date shown beside every answer, cross-converted through the euro. Reference rates are published once each working day for statistical use: they are not the rate a bank or a card will give you. Rates from the dated sample that ships with this page for 2026-09-07. Amounts between two currencies that are not the euro are our own calculation from two published euro rates. Source: European Central Bank euro foreign exchange reference rates.
Common questions
- How many koruna is 100 euros?
- It is 100 multiplied by the koruna-per-euro rate in whichever published set the page loaded, and that set's date is printed beside the answer. In the dated set that ships with this page, the ECB publication of 2026-09-07, one euro was 24.197 koruna, so 100 EUR came to 2,419.70 CZK, 500 EUR to 12,098.50 CZK and 1,000 EUR to 24,197.00 CZK. Those are worked figures from that dated set rather than a rate for today, and the rate moves between publications.
- Is EUR to CZK a published rate or a calculated one?
- Published, and the page says which under every answer. The ECB file is euro foreign exchange reference rates, so every figure in it is that currency per one euro; a pair with a euro leg, EUR to CZK included, uses the published rate as it stands. A pair with no euro leg, such as CZK to USD or ISK to USD, is our own calculation from two published euro rates, and the readout labels it as our calculation rather than as something the ECB printed.
- How often does the rate change here?
- The ECB publishes one set of euro reference rates on each working day, in the afternoon, Central European Time. The server that answers this page asks the ECB for that file at most once every twelve hours and hands the one set it holds, unchanged, to everyone it answers, which is why the observation date sits beside every answer instead of a clock. A Saturday, a Sunday or a public holiday shows the previous working day's set rather than a new one. Past three days the page marks how old the set is, and past seven days it stops converting altogether and prints how old the figures are instead of a number, because a week-old reference rate is not a statement about today. If the file cannot be loaded, the page states the reason and names the date and the origin of whatever set is on screen, so an old figure is never presented as a new one.
- Where is the CZK to EUR page?
- It is this page with the Swap button pressed. Swap sits in the row under the panel, beside Copy, reverses the pair without a reload and keeps the amount you typed, so the same screen answers both directions from the same dated set. In the 2026-09-07 sample the reverse read 1 CZK = 0.0413274 EUR, which is the inverse of 24.197. Keeping one page for the pair is deliberate: two near-identical pages for one rate would split the same answer in half.
- Will I get this rate at a Prague exchange office or from my card?
- No. A European Central Bank reference rate is a daily observation published for statistical use, and it holds no commission, no exchange spread and no card scheme markup. An exchange office, a bank and a card issuer each set their own price with their own margin, so the koruna actually handed over is a different number. What this page gives you is the reference observation for the date printed on it, which is useful as a benchmark rather than as a quote.
- Why does the Rate cell show more digits than the result?
- Because the rate and the amount are rounded for different reasons. The rate prints to six significant figures, 24.197 koruna to the euro in the dated 2026-09-07 sample, which is more than the published file carries. The converted amount prints to two decimal places, with anything smaller than a hundredth keeping four significant figures instead of rounding to nothing. The multiplication itself uses the unrounded rate, so rounding is only ever display.
- Can I check the figure against the ECB?
- Yes, and that is what the date is for. The page prints the ECB's own observation date for the set it used, and the source link under the tool goes to the ECB's euro reference rates page, so you can compare any figure here against the ECB for the same date. The Copy button includes that date, the rate, whether the pair was published or calculated, and the ECB address alongside the converted amount.
- Does the Czech Republic use the euro?
- No, it uses the koruna, which is why this pair exists and why the ECB lists CZK in its daily euro reference rates at all. The file carries the currencies of EU members outside the euro area, the koruna among them, alongside major currencies from further afield. Any currency in the set the page loaded is in both menus, so euros to koruna is one pick away from euros to zloty or forint.
- Is my amount sent anywhere?
- No. This site's route fetches one public ECB file, the same for everyone it answers, and the conversion runs in your browser against that file. Neither the amount nor the pair reaches the ECB or any analytics event. The pair and the amount are remembered in one local storage key so the tool opens where you left it, but this page's setting wins over it and always opens on EUR to CZK; Start over at the top clears what was saved.
