How to use it

How to use currency converter

Estimate currency conversions from cached European Central Bank reference rates and see the source date and stale-data warning.

Estimate the EUR equivalent of a USD invoice using the latest available ECB reference rate.

  1. Enter or paste the values you want to work with.
  2. Review the result and any validation message.
  3. Copy or download the result when the tool provides that action.

How it works

The latest cached ECB EUR reference table supplies the cross-rate, while the amount is converted locally and never sent with the rate request.
