Google announced a new feature within the Google AdSense publisher console to allow publishers to see their performance reports in their own currency of choice.
Now when you click on the columns drop-down in the upper right of your performance report's page, you can click on the Currency drop-down and select a currency from the list. Then choose a currency and click apply. The currency will change to the one you selected.
I should note two things:
(1) The exchange rate fluctuates so these numbers may very well not match the final payment you get from Google.
(2) Changing the currency here will not impact the currency you are paid in.
