Trillion

A trillion is equal to 1012 or 1,000,000,000,000 in short scale Chuquet nomenclature. It is both a square number and cube number, thus it is a zenzicube or 6th power. In the long scale, this number is known as a billion, whereas trillion refers to 1018. In the Indian counting system, it is called a lakh crore or less commonly ten kharab. Other names for trillion include tryriad in CompactStar's version of the -yriad system and tetrillion in Russ Rowlett's Greek-based naming system.

Etymology
The name is derived from the Latin prefix tri-, meaning 3, and the suffix -illion.
