FAQ
How does this currency converter work? +
This currency converter uses USD-based Frankfurter exchange rates embedded at build time. It converts through the shared USD base for every supported currency pair.
Are these exchange rates live? +
No, these are indicative build-time exchange rates, not live trading rates. The timestamp shows the date of the latest embedded rate file.
How do you convert from one currency to another? +
Convert currencies by dividing the amount by the source currency rate and multiplying by the target currency rate. The page does that automatically.
Why does my bank show a different rate? +
Banks, card networks, and exchange desks may add spreads, fees, or use intraday rates. Use this result as an estimate, not a guaranteed settlement rate.
Can I convert USD to EUR? +
Yes, select USD as the source currency and EUR as the target currency. The converter also supports the reverse pair and other major currencies.
