After a trillion, the next number in the commonly used short scale system is quadrillion.
Understanding the names of large numbers extends far beyond a trillion, offering a glimpse into the vastness of mathematics, science, and economics. These names follow a consistent pattern, making it easier to comprehend quantities that seem astronomically large.
The Succession of Large Numbers
In the widely adopted short scale system, numbers increase by factors of one thousand. This means that each new name represents one thousand times the previous one. Following a trillion (10^12), the sequence continues with:
- Quadrillion (10^15)
- Quintillion (10^18)
- Sextillion (10^21)
- Septillion (10^24)
- Octillion (10^27)
- Nonillion (10^30)
- Decillion (10^33)
This progression helps scientists, economists, and other professionals articulate incredibly large quantities found in various fields.
Understanding the Short Scale vs. Long Scale
It's worth noting that different naming conventions for large numbers exist globally. The "short scale" (predominant in the United States and many other English-speaking countries) assigns new names every three powers of ten (e.g., thousand, million, billion, trillion). In contrast, the "long scale" (used in some European countries) assigns new names every six powers of ten, often leading to different values for terms like "billion" or "trillion." For example, a "billion" in the long scale is 10^12, which is a "trillion" in the short scale. However, the sequence provided here follows the short scale, which is the most common context for this question.
A Glimpse at Large Number Values
To further illustrate, here's a table of these numbers and their corresponding values in the short scale:
| Number Name | Value (Short Scale) | Power of Ten |
|---|---|---|
| One | 1 | 10^0 |
| Thousand | 1,000 | 10^3 |
| Million | 1,000,000 | 10^6 |
| Billion | 1,000,000,000 | 10^9 |
| Trillion | 1,000,000,000,000 | 10^12 |
| Quadrillion | 1,000,000,000,000,000 | 10^15 |
| Quintillion | 1,000,000,000,000,000,000 | 10^18 |
| Sextillion | 1,000,000,000,000,000,000,000 | 10^21 |
| Septillion | 1,000,000,000,000,000,000,000,000 | 10^24 |
| Octillion | 1,000,000,000,000,000,000,000,000,000 | 10^27 |
| Nonillion | 1,000,000,000,000,000,000,000,000,000,000 | 10^30 |
| Decillion | 1,000,000,000,000,000,000,000,000,000,000,000 | 10^33 |

Practical Applications of Large Numbers
While these numbers might seem abstract, they are regularly encountered in various real-world scenarios:
- Economics: National debts and GDPs of major economies often run into trillions of dollars. Future projections or extreme market scenarios might involve quadrillions.
- Astronomy: Distances between celestial bodies, the number of stars in galaxies, or the estimated age of the universe often require these extremely large figures. For example, the estimated number of atoms in the observable universe is roughly 10^80, a number far beyond a decillion.
- Science and Computing: In fields like particle physics, genetics, or advanced computing, calculations involving permutations, combinations, or data storage capacities can quickly reach into the quintillions and beyond.
- Probability: The odds of highly unlikely events, such as winning multiple major lotteries consecutively, can be expressed with such vast numbers.
Understanding the sequence and magnitude of these numbers is fundamental to grasping the scale of our universe and the complex systems within it.
