# Plural form of a billion

Hello.

one billion = 10^9 = one thousand million

How do you say the plural of it? I have translated it in a dictionary to find out that the plural of a billion is: "billions". But that is weird, because:

1) "The net worth of Larry Page is 61.3 billion dollars."

or should it be:

2) "The net worth of Larry Page is 61.3 billions dollars."

Another example. Should I write:

3) "I see billion of stars." (not meaning one billion, meaning a lot)

or, should it be:

4) "I see billions of stars."

I think that million has the same issue.. (also: "His net worth is two million dollars.", why is it not millions?)

Thank you.

Units like billion and million are not generally pluralized, except when there is no number attached to them: They owe \$10 billion, but they owe billions.

So the 1) and 4) sentence is correct then. Right?

(1) and (4) are fine.
why is it not millions?
Because attributive nouns (nouns which come before other nouns) are usually singular.

This applies to most numbers when the unit is part of a specific number. He owes two hundred dollars. He owes hundreds of dollars
