How to use Currency converter

Convert between about 30 major currencies using the daily reference exchange rates published by the European Central Bank and other central banks.

  • Latest rates, or historical rates for any working day since 1999
  • Quick table of common amounts in both directions
  • Rates are saved in your browser, so the converter keeps working offline

This is the one tool on the site that makes a network request: it fetches rates from the free Frankfurter API. Your amounts are never sent. Banks and card providers add a margin, so the rate you're actually charged will differ.
