You may be thinking of the binary number system.
1 million has 6 zeros (1,000,000) in any system
There are nine zeros in a gillion, which is a number in the Gillion system which isn't commonly used.
quindecillion (American System) or octillion(European System).The American System of naming large numbers has billion to be 1 with nine zeros, while the European System calls milliard for 1 with nine zeros, and a billion is 1 with 12 zeros, so it depends on what system you use.

There are nine zeros in a gillion, which is a number in the Gillion system which isn't commonly used.
"Drillion" does not appear in either the American or the British system of numeration for denominations up to 10600. The closest name on either list is the "trillion", meaning '1' followed by 12 zeros (American) or 18 zeros (British). The next designation is "quadrillion". In the American system, '1' with 15 zeros. In the British system, '1' with 24 zeros.

12 of them.
A duodecillion is equal to 1 followed by 39 zeros in the short scale (American) numbering system. In the long scale (British) numbering system, a duodecillion is equal to 1 followed by 72 zeros. Therefore, in the short scale system, there are 39 zeros in a duodecillion.
That's a system that specifies how data is to be stored as ones and zeros in a computer.
1000000000
The system of representing numbers with a system of ones and zeros is called binary code; examples would be...12 = 110015 = 111120 = 10100 and so on.
One million in the US system is a one followed by six zeros: 1,000,000.
