1000000000 (nine zeros)
In the US, 1 billion is 1 x 109 so 323.3 billion is 323,300,000,000.
On the US short scale (1 billion = 1000 million) :10,130,000,000On the long scale (1 billion = 1 million million) : 10,130,000,000,000, which is trillions on the US scale.
1 billion = 1,000,000,000
1,000,000,000 (US or short scale, 1 x 109)
1,000,000,000 = 1 billion.
As a number it is: 1,000,000,000 = 1 billion

1 and one half billion can be written as 1.5 billion.
Assuming you mean billion*billion*billion = It is 1*10^27.
