Answer 6

it depends on whom you ask

Answer 7

everybody i came across told me it has 9 zeros hmm

Answer 8

Ahh the alternative 10^12 makes sense
The European standard is that 1 billion = 1,000,000,000,000, but this is no longer commonly used in Britain and any current British news article that mentions billions will mean 10^9, not 10^12.
