Currency converter

How this conversion works

The rate service supplies one reference-rate table with EUR as its base. For two non-EUR currencies, we divide the target currency’s EUR-base rate by the source currency’s EUR-base rate. The calculation happens in your browser.

Reference rates are not transaction quotes

The estimate does not include a bank, card, cash-exchange, or transfer provider’s markup or fees. The European Central Bank says its reference rates are for information purposes and strongly discourages using them for transactions. Check the quote from the provider you would actually use before moving money. Read the ECB reference-rate notice.

What leaves your browser

SterlingCat requests the shared currency-rate list from the InnoviCat rate endpoint. That request contains neither your amount nor your selected currency pair. Your inputs remain in this browser; a copied share link carries them in the URL fragment so the recipient can reproduce the estimate. When you explicitly change or swap the pair, SterlingCat remembers that pair in this browser for next time. It does not save the amount.
