Ever wonder how much money we are talking about when we say a billion or trillion dollars. Do these big numbers fancy you?
In this guide, you’ll learn how many zeroes there are in a million, billion, and trillion. For numbers with lots of zeroes, it can be hard to get a real sense of scale.
Right now there are nearly 31.5 million seconds in a year, 1.04 Million Megabytes(MB) and 1.073 Billion KiloBytes in a TerraByte (TB).
Students or adults often get confused while calculating the no of zeroes in one million, billion, trillion. It is difficult to remember how many zeroes are there in these nos as we use them very rarely in our daily lives.
Here we bring you how to zeroes contribute to each number. Let’s dive into the details,
| Ten | 10 | 1 Zero |
| Hundred | 100 | 2 zeroes |
| Thousand(Kilo) | 1,000 | 3 Zeroes |
| Ten Thousand | 10,000 | 4 Zeroes |
| Hundred Thousand(One Lac) | 100,000 | 5 Zeroes |
| One Million | 1,000,000 | 6 Zeroes |
| Ten Million | 10,000,000 | 7 Zeroes |
| 100 Million | 100,000,000 | 8 Zeroes |
| 1 billion | 1,000,000,000 | 9 Zeroes |
| 10 Billion | 10,000,000,000 | 10 Zeroes |
| 100 Billion | 100,000,000,000 | 11 Zeroes |
| 1Trillion | 1,000,000,000,000 | 12 Zeroes |
| Quadrillion | 1,000,000,000,000,000 | 15 Zeroes |
| Quintillion | 1,000,000,000,000,000,000 | 18 Zeroes |
| Sextillion | 1,000,000,000,000,000,000,000 | 21 Zeroes |
| Septillion | 1,000,000,000,000,000,000,000,000 | 24 Zeroes |
| Octillion | 1,000,000,000,000,000,000,000,000,000 | 27 Zeroes |
One can go on like this and will never end, just keep adding zeroes. The biggest number Googolplex has 1 followed by 10¹⁰⁰ Zeroes.
How many Zeroes in Multiplication factors like Mega, Giga?
Decimal and Binary systems use prefixes to denote the number of zeroes in each number.
| Symbol | Name | Multiplication Factor | Zeroes |
| E | Exa | 10¹⁸ | 1000000000000000000 |
| P | Peta | 10¹⁵ | 1000000000000000 |
| T | Tera | 10¹² | 100000000000 |
| G | Giga | 10⁹ | 100000000 |
| M | Mega | 10⁶ | 100000 |
| k | Kilo | 10³ | 100 |
| h | Hecta | 10² | 10 |
| da | Deca | 10¹ | 0.1 |
| d | Deci | 10⁻¹ | 0.1 |
| c | Centi | 10⁻² | 0.01 |
| m | Milli | 10⁻³ | 0.001 |
| µ | Micro | 10⁻⁶ | 0.000001 |
| n | Nano | 10⁻⁹ | 0.00000001 |
| p | Pico | 10⁻¹² | 0.000000000001 |
| f | Femto | 10⁻¹⁵ | 0.000000000000001 |
| a | Atto | 10⁻¹⁸ | 0.000000000000000001 |
What is Mega, Giga and Tera?
In the information technology field, there are many different terms that describe computer data storage. While these terms are used interchangeably by people to denote the amount of data, they actually have very specific definitions that distinguish them from one another.
Computer data is measured in Bits and Bytes. These are used to measure data transfers, data sizes, and many more.
Let’s take a closer look at the most common ones: Mega, Giga, and Tera. They all come from the Greek language and mean 1 million, 1 billion, and 1 trillion.
| Unit | Value |
| 1 Byte | 8 Bits |
| 1 KiloByte (KB) | 1024 Byte |
| 1 Megabyte(MB) | 1024 Kilobytes |
| 1 Gigabyte(GB) | 1024 Megabytes |
| 1 Terabyte(TB) | 1024 Gigabytes |
| 1 Petabyte(PB) | 1024 Terabytes |
| 1 Exabyte(EB) | 1024 Petabytes |
| 1 Zettabyte(ZB) | 1024 Exabytes |
Conclusion:
We all use the word “million” and “billion,” it’s easy to forget that these really are very big numbers. This chart helps us remember just how big these numbers really are, and how much bigger a trillion is than a billion.
