A quintillion is equal to 1018 in the short scale, or 1030 in the long scale.[1][2]
Written out in decimal form quintillion (in the short scale) is:
In long scale:
This number is also called hexillion in Russ Rowlett's Greek-based naming system.[3]
Aarex Tiaokhiao calls this number hetillion.[4] He also gave name ocdoocol and 18-noogol, referring to the short scale value of this number.[5]
Wikia user NumLynx gave the name sexasand for this number's short scale value.[6]
Nicolas Chuquet coined tryllion for 1018 (not to be confused with 1032), according to the Triparty en la science des nombres, which was previously lost and not rediscovered until 1880. [7][8] Later it became trillion in long scale.

- The SI prefix exa- multiplies by one quintillion.
- The Earth's cross section has an area of about 1.275 quintillion square centimeters. [11]
- By one estimate, there are 20 quintillion living animals on Earth.[12]
- a tower of a quintillion one dollar bills would aproximately measure 1.099*10^20m in height.
- The half-life of Bismuth-209 is approximately 20 quintillion years.
As a banknote denomination[]
Only the Hungarian pengő had banknotes with this number in the denomination.
