Trillion

However, since 1974, official UK statistics have used the short scale.

[1][2] American English has always used the short scale definition.

During the height of hyperinflation in Zimbabwe in 2008, people became accustomed to speaking about their daily expenses in terms of trillions.

[2] When Italy used the lira as currency, eventually converted at about 2,000 lira to the euro, it was found that Italians were more comfortable with words for large numbers such as trillion than British people.

[2][3] As a result, it was mainly used to express the concept of an enormous number, similar to the words zillion and gazillion.
