A Yobibyte is a unit of digital information storage that stands for 2 to the 80th power or 1,208,925,819,614,629,174,706,176 bytes. It belongs to the binary system of measuring storage capacity, which uses a base of 2, unlike the decimal system which uses a base of 10. To put it into perspective, a Yobibyte is approximately 1.2 septillion bytes or about 1 trillion gigabytes.


The phonetics of the keyword “Yobibyte” is: yoʊbaɪbaɪt

Key Takeaways

  1. Yobibyte is a data measurement unit which is part of the binary system of data storage measurement. It is equivalent to 280 or 1,208,925,819,614,629,174,706,176 bytes.
  2. It is often compared to the Yottabyte, a decimal unit of measurement. While they sound similar, a Yobibyte is much larger than a Yottabyte – 1 Yobibyte is approximately equal to 1.2 Yottabytes.
  3. The term Yobibyte comes from the combination of ‘Yotta-‘ meaning “eight” in Greek, ‘bi’ from binary, and ‘-byte’ a common unit of digital information storage.


The term Yobibyte is an important terminology in technology as it represents a high level of data storage capacity. In fact, it denotes the largest standard data size currently formally recognized in computer science. Specifically, one Yobibyte is equal to 1,208,925,819,614,629,174,706,176 bytes, or simply 2 to the 80th power bytes. As data storage and transfer increase rapidly in this big data era, more substantial units such as Yobibyte become critical for detailing capacity and actual data handling in high-performance computing and data-intensive applications, including cloud storage, machine learning, and various scientific computing. Therefore, understanding the term Yobibyte can aid in comprehending and managing the enormous volumes of data generated in today’s digital world.


The term Yobibyte is principally used in the realm of computing and data storage systems. As an extensive unit of digital information storage, it aids in quantifying and marking the massive capacity in which data can be stored, serving a purpose similar to other units like kilobytes, megabytes, gigabytes, etc. The distinction, though, is that a Yobibyte signifies a much larger volume of information; one Yobibyte equals approximately 1.20892582 × 10⁴⁰ bytes. It is especially useful in settings where gargantuan data sets are handled regularly, such as in cloud computing, advanced scientific computations, digital media archiving, and large-scale databases. The unique aspect about a Yobibyte, as compared to a Yottabyte, is that it adheres to the binary system (base 2) of data measurement, making it more compatible with the inherent binary nature of computing systems. This facilitates efficiency and accuracy in data measurement, processing, and storage. These features particularly assist in optimizing digital operations in several sectors, including research, technology, business, entertainment, etc, where colossal data resources are processed, handled, stored, or transferred on a daily basis. Consequently, the concept of a Yobibyte becomes integral in describing digital information dimensions effectively and accurately in various technological contexts.


The term “Yobibyte” is a high-capacity data measurement unit from the binary system, often used in computer science. In broad terms, a Yobibyte is approximately equivalent to 1.2 trillion gigabytes, but it’s rarely used in practice. Currently, there are no real-world examples where “Yobibyte” is used, as it’s not yet applicable in our existing technology. The highest measure generally used today is Exabytes and Zettabytes (1 Zettabyte equals 1 million petabytes or 1 billion terabytes), primarily when measuring global internet traffic or large-scale data storage. Even the entire digital universe today does not amount to one Yobibyte.

Frequently Asked Questions(FAQ)

**Q1: What is a Yobibyte?**A1: A Yobibyte (YiB) is a standard unit of measurement in computing that represents data storage capacity. It is equivalent to 2 to the 80th power bytes or about 1.21 yottabytes in the decimal system.**Q2: How is the term Yobibyte abbreviated?**A2: Yobibyte is abbreviated as “YiB”.**Q3: How does a Yobibyte compare to other data storage units?**A3: A Yobibyte is larger than a Pebibyte, Tebibyte, Gibibyte, Mebibyte and Kibibyte. It is the largest standard binary storage unit.**Q4: Where is the term Yobibyte commonly used?** A4: Yobibyte is most commonly used in computer science and information technology when discussing data storage, data transmission, memory, or system information.**Q5: How did the Yobibyte get its name?** A5: “Yobi” stands for octillion, and “byte” is a standard unit of digital information.**Q6: Why do we need the term Yobibyte?**A6: Yobibyte aims to eliminate confusion that could arise from the traditional system, where, for example, a gigabyte could mean 1000^3 bytes or 1024^3 bytes. Size comparison and conversion become easier using a Yobibyte.**Q7: Is there something larger than a Yobibyte?**A7: As per the standard system of units, there’s no term established for a quantity larger than a Yobibyte in binary units.**Q8: What’s the difference between a Yottabyte and a Yobibyte?**A8: The main difference between the two lies in their size and the system they are based on. A Yottabyte (YB) is based on the decimal or base-10 system and is equivalent to 1000^8 bytes, while a Yobibyte is based on the binary or base-2 system and is equivalent to 2^80 bytes.
