- Not to be confused with yoctillion.
An octillion is equal to 1027 in America, or 1048 in France and Germany.[1]
A square of 1027 square centimeters in area compared to the average orbital distances of the inner planets. The sun is drawn at a scale about 50x larger and the planets at a scale about 500x larger than the remainder of the diagram.
A radius of 1027 meters, compared to the observable universe
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] and Aarex Tiaokhiao's googology site[3] give the name ennillion for this number.
The number (in short scale) is also called tre-bitillion by SuperJedi224.[4]
It is 28 digits long in short scale, and 49 digits long in long scale.
Decimal
- 1,000,000,000,000,000,000,000,000,000 - short scale
- 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 - long scale
Examples
- The earth has a mass of about 5.98 octillion grams.
- The mass of the sun is about 1.989 octillion metric tons.
- The volume of the sun is about 1.412 octillion cubic meters.[5]
- An octillion dollars in 100 dollar bills would cover the US with a layer of 1000 km (625 miles) thick.
- A square of one octillion square centimeters in area would fit entirely inside the orbit of Mars (the diagonal of such a square would be about 2% smaller than the minor axis of its orbit).
- There are over 7 octillion atoms in the human body.
- There is over 169.5 octillion ways to play the first ten moves in chess.[6]
- The Hungarian pengő had the highest rate of hyperinflation recorded, reaching 400 octilion pengős.
