- For Tiaokhiao's decillion, see nonillion.
A decillion is equal to 1033 in short scale, or 1060 in long scale.[1] It is 34 digits long in short scale, and 61 digits long in long scale.
In the long scale, 1033 is called quintilliard, which is commonly used in France and Germany.
This number is also called hendekillion in Russ Rowlett's Greek-based naming system.[2]
Aarex Tiaokhiao gave the name mecillion, referring to the value of this number.[3]
Wikia user NumLynx gave the name undecisand for this number.[4]
BlankEntity calls this number Doocol.[5]
This number can be imagined as a cube with a sidelength of 100 billion.
