novemnonagintillion is equal to 10300 in America, or 10594 in France and Germany.[1] The short scale value is also equal to googol3.

In the long scale which is commonly used in France and Germany, 10300 is called quinquagintillion.

This number is also called hectillion in Russ Rowlett's Greek-based naming system of zillions.[2]

Aarex Tiaokhiao calls this number centillion (not to be confused with 10303).[3] He also gave names troohol and 300-noogol, referring to the short scale value of this number.[4]

See Prefix 10300 for prefixes that multiply by 1 novemnonagintillion.
