Treasury exchange rate converter
Convert a foreign currency amount to U.S. dollars with the Treasury Reporting Rates of Exchange, the rates the Treasury publishes for use in federal reporting.
How it works
The Treasury publishes a table of exchange rates, expressed as units of foreign currency per one U.S. dollar. The tool divides your amount by that rate.
Some currencies appear with more than one rate in the Treasury data. The tool uses the first listed row for each currency.
Worked example
Dividing 100,000 euros by 0.881 gives 113,507.38 USD. Dividing 100,000 Swiss francs by 0.835 gives 119,760.48 USD.
What this tool does not do
The result is an illustration of the published rate. The tool does not state which rate a taxpayer must use for any form. The instructions for each form say which rate or method applies.
