Fill in the fields and the result will appear here automatically.
Convert a USD amount into EUR using the saved reference coefficient. This page fixes the direction USD → EUR and shows the source date for the euro coefficient.
How it works
Formula and logic
USD is the common base with coefficient 1. EUR amount = USD amount × the saved EUR coefficient. For ECB data, that coefficient is the reciprocal of the published USD per 1 EUR. The saved coefficient is rounded and the result normally shows two decimals; it is not a customer sale price for euros.
Example
Teaching example using saved data: 100 USD × 0.89253838 / 1 = 89.25 EUR. Actual source dates: ECB 2026-10-05. With a zero amount: 0 USD = 0 EUR.
