How many zeros are in 1 TRILLION -?

Answer 1

In the US, there are 12, excluding the 2 zeroes past the decimal. (see below)

$1,000 is one thousand US dollars.

$1,000,000 is one million US dollars.

$1,000,000,000 is one billion US dollars.

$1,000,000,000,000 is one trillion US dollars.

Short Scale and Long Scale

The "short scale" used in the US, UK, and elsewhere assigns number names (thousand, million, billion, trillion, quadrillion) by thousands.

On the short scale, there are 12 zeros in a trillion (1012). It is 1,000,000,000,000.

The traditional long scale, still used in many areas of the world, advances number names by millions, with intermediate names for the thousands (milliard, billiard, trilliard). On the long scale, a billion is a million million, and a trillion is a million billion.

On the long scale, there are 18 zeros in a trillion (1018). It is 1,000,000,000,000,000,000.

Answer 2

The "short scale" used in the US, the UK, and elsewhere assigns number names (thousand, million, billion, trillion, quadrillion) by thousands.

On the short scale, there are 12 zeros in a trillion(1012).

It is 1,000,000,000,000.

The traditional long scale, still used in some areas (Europe, Latin America), advances number names by millions, with intermediate names for the thousands (milliard, billiard, trilliard). On the long scale, a billion is a million million, and a trillion is a million billion.

So on the long scale, there are 18 zeros in a trillion (1018).

It is 1,000,000,000,000,000,000.
