The Number 1,000,000,000 In English this number is a billion. This is very tricky for nations where 'a billion' has 12 zeros. 1,000,000,000,000 in English, however, is a trillion.

But don't worry, these numbers are even a bit problematic for native speakers: for a long time the British 'billion' had 12 zeros (a number with 9 zeros was called 'a thousand million'). Now, however, also in British English 'a billion' has 9 zeros. But from time to time this number still causes confusion (just like this paragraph, I'm afraid). ;o)

Singular or Plural? Numbers are usually written in singular.

two hundred Euros

several thousand light years

The plural is only used with dozen, hundred, thousand, million, billion, if they are not modified by another number or expression (e.g. a few / several).

hundreds of Euros

thousands of light years
