How many zeros are in "one billion" where you live?

I know this sounds like a strange question. But in fact, the English names for large numbers are not the same in all countries. I live in the United States, and for us, "one billion" is the name for

1,000,000,000

But in some countries, this is called "a thousand million", and the name "one billion" refers to

1,000,000,000,000

which we call "one trilliion" in the US.

I'm curious about how this varies around the world: Please respond with your country and the number of zeros ( 9 or 12). Or if you simply know of the usage in a country other than your own, that would be good too.

I realize that not everyone ever thinks about numbers this big, so if you do not know, please do not guess :)

thanks
