Answer 2

On the US scale ("short scale") a billion is a thousand million, and a trillion is a thousand bllion.

1 trillion = 10^12 = 1,000,000,000,000

On the European "long scale" a billion is a million million, and a trillion is a million billion.

1 trillion (Europe) = 10^18 = 1,000,000,000,000,000,000
