- "Heptillion" redirects here. It is not to be confused with hepillion.
A sextillion is equal to 1021 in short scale, or 1036 in long scale.[1][2]
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:
In long scale:
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.[3]
Aarex Tiaokhiao gave the name heptillion, referring to the value of this number.[4]
Wikia user NumLynx gave the name septasand for this number's short scale value.[5]
