How many German Marks were equivalent to US dollars during World War 2?

During World War II, the exchange rate between the German Mark and the US dollar varied significantly due to the economic conditions of the time. At the beginning of the war, the exchange rate was around 2.5 German Marks to 1 US dollar. However, as the war progressed and Germany's economy deteriorated, the value of the Mark plummeted, reaching extreme levels of inflation.
