A quintillion is equal to 1018 in America, or 1030 in France and Germany.[1]
Written out in decimal form quintillion (in the short scale) is:
1000000000000000000
In long scale:
1000000000000000000000000000000
This number is also called hexillion in Russ Rowlett's Greek-based naming system.[2]
Aarex Tiaokhiao calls this number hetillion.[3] He also gave name ocdoocol and 18-noogol, referring to the short scale value of this number.[4]
