A sextillion is equal to 1021 in short scale, or 1036 in long scale.[1][2][3][4]
A sextillion dollars in 100 dollar bills in comparison to the United Kingdom and Ireland.
It is 22 digits long in short scale, or 37 digits long in long scale.
Written out in decimal form sextillion (in the short scale) is:
1000000000000000000000
In long scale:
1000000000000000000000000000000000000
In the long scale, 1021 is called trilliard, which is commonly used in France and Germany.
This number is also called heptillion in Russ Rowlett's Greek-based naming system.[5]
Aarex Tiaokhiao gave the name heptillion, referring to the value of this number.[6]
Wikia user NumLynx gave the name septasand for this number's short scale value.[7]
DeepLineMadom calls the number troo-enicol, and is equal to 10[3]21 in DeepLineMadom's Array Notation.[8]

As a banknote denomination[]
Only the Hungarian pengő had banknotes with this number in the denomination, but they were never issued; in fact, it was the highest banknote denomination ever printed.
