An octillion is equal to 1027 in America, or 1048 in France and Germany.[1]

In the long scale, 1027 is called quadrilliard, which is commonly used in France and Germany.

Both Russ Rowlett's Greek-based naming system[2] give the name ennillion for this number.

Donald Knuth calls this number xoniad, and it's equal to using the -yllion system.
