Currency Converter with Published Rates
Use cached periodic data from a suitable provider, and show the source, update time, and usage limits.
Rates come from Frankfurter, which publishes the European Central Bank reference rates once per working day. SAR, AED, EGP, and MAD are not in that list; use the manual exchange rate calculator with your bank’s rate.
Your result
Choose two currencies and press Convert.
A reference rate, not the price a bank or exchange office will give you: they add their own margin and fees.
How to use it
- Choose the two currencies.
- Type an amount, or leave it blank to use 1.

Tool details and privacy
Type an amount and two currencies from the Frankfurter list. The page asks this site for the cached published rate, then shows the source and the date. SAR, AED, and EGP are not in that list.
The figure comes from the published response. If that response is missing, the page shows an error instead of a made-up rate.
Options
- Blank amount means 1.
- The same currency does not send a request.
- The rate is cached for about six hours and rounded to 4 decimals.
Limits
- Only currencies Frankfurter publishes can be converted.
- A recorded sample on this page is not the live rate. The button uses the current response.
- 1,250 is refused because the comma is ambiguous. 1250. is accepted while typing and becomes 1250.
Privacy
What you type is sent to this site so it can ask a public service or DNS. It is not stored in the tool analytics. A failed lookup is an error, not a made-up result.
