The number 1,000,000,000,000 (10 to the power of 12), or one thousand billion. In German-speaking countries and most European countries, this "long scale" is used, in contrast to the "short scale" in English, where "billion" means eine Milliarde.
example
Die Staatsverschuldung des Landes übersteigt eine Billion Euro.
The country's national debt exceeds one trillion euros.
Usage tips
False friend
Careful: the German "Billion" (trillion) is not the same as the English "billion". A German Billion is a million million (1,000,000,000,000), which is called "trillion" in English. The English "billion" is "eine Milliarde" in German.
EXAMPLE
Das Unternehmen hat einen Wert von fast einer Billion Euro.
The company is worth almost one trillion euros.
Typical context
The word "Billion" (trillion) is used almost exclusively in contexts involving extremely large numbers, such as economics (national debt, company value) or astronomy (distances in space).
EXAMPLE
Die Staatsschulden sind auf über zwei Billionen Euro gestiegen.
The national debt has risen to over two trillion euros.
Use with nouns
When a noun follows "Billion" (trillion) or "Billionen" (trillions), this noun is in the plural and used without an article.
EXAMPLE
Auf der Erde leben mehrere Billionen Insekten.
Several trillion insects live on Earth.

Billion vs Million
million
'die Million' and 'die Billion' are both number words for very large quantities. The difference is enormous: one million is 1,000,000, while eine Billion is 1,000,000,000,000. So eine Billion is one million million, or one thousand Milliarden. Learners may confuse the words because they sound similar and because the English word 'billion' is used differently. In German, 'die Billion' is much larger than 'die Milliarde' and much larger than 'die Million'.
Billion
Die Schulden des Landes liegen bei über einer Billion Euro.
The country's debt is over one trillion euros.
Million
Für das neue Museum spendet die Firma eine Million Euro.
The company is donating one million euros for the new museum.
