How many zeroes are in 1 trillion? / Un trilione a 12 o 18 zeri ? [Rif.: Alzato di un trilione il tetto del debito USA]

How many zeroes are in 1 trillion? [Math and Arithmetic]
Answer:
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 (10^12).
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 (10^18).
It is 1,000,000,000,000,000,000

Un trilione è il numero naturale che equivale a un milione di bilioni, cioè un milione alla terza (1.000.000.000.000.000.000 o 1018), succede il 999.999.999.999.999.999 e precede il 1.000.000.000.000.000.001. Il trilione equivale anche a un milionesimo di quadrilione. NelSistema Internazionale, il prefisso per il trilione è exa.
Negli Stati Uniti e nel mondo anglosassone in genere Trillion equivale a mille miliardi(uguale a 10^12).

House Democrats met the deal with scorn, indicating they would inflict maximum political pain by making Republicans either break a campaign promise to carry it to passage or defy their leaders. But other Democrats were more sanguine. The president had said he would not sign a short-term debt ceiling increase, but a senior administration official said that as long as there were no surprises, the White House was likely to accept the House’s offer. Most important, the official said, Republicans had broken from the “Boehner rule” imposed in 2011: any debt ceiling increase was to include a dollar-for-dollar spending reduction.
The decision represents a victory — at least for now — for Mr. Obama, who has said for months that he will not negotiate budget cuts under the threat of a debt default. By punting that threat into the spring, budget negotiations instead will center on two earlier points of leverage: March 1, when $1 trillion in across-the-board military and domestic cuts are set to begin, and March 27, when a stopgap law financing the government will expire...
