A sextillion is equal to 1021 in America, or 1036 in France and Germany.[1]
In the long scale, 1021 is called trilliard, which is commonly used in France and Germany.
This number is also called heptillion in Russ Rowlett's Greek-based naming system.[2]
Aarex Tiaokhiao gave the name heptillion, referring to the value of this number.[3]
It is the smallest -illion number whose successor isn't squarefree.[4]

Examples
- The volume of the earth is about 1.085 sextillion cubic meters.
- The earth has a mass of about 5.98 sextillion metric tons.
- There are about 6 sextillion cups of water in all the oceans of the world.
- The distance between one end of the universe and the other may be about 87.9 sextillion miles or 141 sextillion kilometers.[5]
- You could fit 615 earths in a flat layer with an area of one sextillion square centimeters.[6]
- The SI prefix zetta- multiplies by one short-scale sextillion.
As a banknote denomination
Only the Hungarian pengő had banknotes with this number in the denomination, but they were never issued; in fact, it was the highest banknote denomination ever printed.
