How many zeroes are there in quintillion?

Too easy of choices. Should at least change "6" to "15" (perhaps quintillion similar to spanish quince) or something higher than "18".

Just when I thought the American billions and trillions system makes sense, I read the explanation for Britain. Now I still don't know if I am a billionaire or trillionaire!!

that is a BIG number!!

wait quintillion exist?,tell me if you know.

Some greedy CEO Out there wants to be one! Horendous Working conditions and Long hours for the employees?
