What is us airmail postage to Germany for 1 oz letter?

As of my last knowledge update in September 2021, the postage for sending a 1-ounce letter from the United States to Germany via First-Class Mail International service (the equivalent of airmail for letters) was $1.20.

However, postal rates can change over time, so it's a good idea to verify the current postage rates to Germany on the United States Postal Service (USPS) website or using the USPS postage rate calculator.
