A pebibyte (PiB) is a unit of digital information storage equal to 250 bytes, which is exactly 1,125,899,906,842,624 bytes (or 10245 bytes). It uses the binary prefix 'pebi-' established by the International Electrotechnical Commission (IEC). The pebibyte was created to provide an unambiguous measurement for byte multiples based on powers of 2, distinguishing it from the petabyte (PB), which is based on the decimal prefix 'peta-' (1015 or 1,000,000,000,000,000 bytes).
An exabyte (EB) is a unit of digital information storage equal to 10¹⁸ bytes (one quintillion bytes). It uses the standard SI decimal prefix 'exa-'. One exabyte is equivalent to 1,000 petabytes or 1,000,000 terabytes.
Precise definitions:
- 1 exabyte (EB) = 1,000,000,000,000,000,000 bytes (exactly 10¹⁸)
- 1 EB = 1,000 petabytes (PB)
- 1 EB = 1,000,000 terabytes (TB)
- 1 EB = 8,000,000,000,000,000,000 bits (8 exabits)
Relationship to binary units:
- 1 exabyte (EB) ≈ 0.867 exbibytes (EiB)
- 1 exbibyte (EiB) = 1,152,921,504,606,846,976 bytes = 2⁶⁰ bytes
- 1 EiB ≈ 1.1526 EB (15.26% larger)
Exabyte (EB) vs. Exbibyte (EiB): Massive Scale Distinction
At exabyte scale, even small percentage differences matter enormously:
Exabyte (EB) — Decimal prefix:
- Exactly 1,000,000,000,000,000,000 bytes (10¹⁸)
- Based on SI standard (powers of 10)
- Used by cloud providers, data centers, global statistics
- Standard for internet traffic and data creation metrics
Exbibyte (EiB) — Binary prefix:
- Exactly 1,152,921,504,606,846,976 bytes (2⁶⁰)
- Based on binary powers (powers of 2)
- Used by technical specifications, scientific computing
- Standard for certain supercomputing and research contexts
Why the 15% difference is critical:
- 1 EB = 0.867 EiB (significant difference)
- Data center planning: 100 EB = 86.7 EiB of actual capacity
- Scientific datasets: Precision matters for resource allocation
- Global statistics: Internet traffic measured in EB (decimal)
Exabyte (EB) vs. Exabit (Eb): Global Data Distinction
Another critical distinction at massive scale:
Exabyte (EB):
- Measures storage capacity (data at rest)
- 1 EB = 1,000,000,000,000,000,000 bytes
- Used for: cloud storage, data centers, archives
Exabit (Eb or Ebit):
- Measures data transfer (data in motion)
- 1 Eb = 1,000,000,000,000,000,000 bits
- Used for: network capacity, global internet bandwidth
- 1 exabyte = 8 exabits (since 1 byte = 8 bits)
Real-world example:
- Global internet traffic: ~200 EB annually
- Network capacity: Measured in Eb/s (exabits per second)
Note: The Pebibyte is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Exabyte belongs to the imperial/US customary system.
History of the Pebibyte and Exabyte
The prefix 'pebi-' (representing 250) was defined by the IEC in 1998 alongside other binary prefixes (kibi-, mebi-, gibi-, tebi-, exbi-). Before this standard, the SI prefix 'peta-' (P) was ambiguously used to represent both 1,000,000,000,000,000 (1015, as per its SI definition) and 1,125,899,906,842,624 (250) in computing contexts, especially for very large data volumes. This led to significant confusion when comparing storage capacities advertised by manufacturers (often using decimal prefixes) and those reported by operating systems or used in technical specifications (often using binary interpretations). The introduction of the pebibyte (PiB) aimed to resolve this ambiguity by providing a specific term for 250 bytes.
The "Exa-" Prefix Origins (1975)
International standardization for extreme scales:
1975: 15th General Conference on Weights and Measures (CGPM):
- Officially adopted "exa-" as the SI prefix for one quintillion (10¹⁸)
- Derived from Greek "ἕξ" (hex) meaning "six" (representing 10¹⁸)
- Part of the expanded SI prefix system: peta (10¹⁵), exa (10¹⁸), zetta (10²¹), yotta (10²⁴)
Scientific context before computing:
- Originally used in physics for extremely large measurements
- Theoretical unit until digital data made it practical
Computing Era: EB Becomes Reality (1990s-2000s)
When exabytes became measurable:
1990s: Internet and digital libraries:
- World Wide Web growth created measurable data at EB scale
- First large digital libraries reached petabyte scale
- Scientific computing began generating EB-sized datasets
2000s: Cloud computing and big data:
- 2006: Amazon S3 launch marked practical EB-scale storage

- 2012: Facebook data center design for EB-scale storage
- 2015: Microsoft announces EB-scale cloud capacity
- 2020s: Major cloud providers operate at multi-EB scale
EB vs. EiB: The Massive Scale Ambiguity
Confusion at the highest scales:
The root problem: Even at exabyte scale, decimal vs. binary matters
2010s: Technical vs. consumer usage:
- Cloud providers: Use EB (decimal) for marketing and statistics
- Scientific computing: Use EiB (binary) for technical specifications
- Network engineering: Mix both depending on context
Current adoption:
- Consumer/global stats: EB (decimal) dominates
- Technical specifications: EiB (binary) for precision
- Hybrid usage: Context determines which is appropriate

Additional Unit Information
About Pebibyte (PiB)
How many bytes are in a pebibyte (PiB)?
There are exactly 250 bytes in 1 pebibyte (PiB). This equals 1,125,899,906,842,624 bytes.
How many tebibytes (TiB) are in a pebibyte (PiB)?
There are 1,024 tebibytes (TiB) in 1 pebibyte (PiB). This follows the binary prefix system where 1 PiB = 250 bytes and 1 TiB = 240 bytes, and 250 / 240 = 210 = 1,024.
What is the difference between a pebibyte (PiB) and a petabyte (PB)?
A pebibyte (PiB) represents 250 bytes (1,125,899,906,842,624 bytes), using the IEC binary prefix 'pebi-'. A petabyte (PB) typically represents 1015 bytes (1,000,000,000,000,000 bytes), using the SI decimal prefix 'peta-'. A pebibyte is approximately 12.6% larger than a petabyte (1 PiB ≈ 1.126 PB). Use PiB for precision in binary contexts (like large-scale OS reporting, HPC storage) and PB for decimal contexts (like marketing large storage systems) or when the specific definition is clarified.
What is the difference between a pebibyte (PiB) and a pebibit (Pib)?
A pebibyte (PiB) measures information in bytes, while a pebibit (Pib) measures information in bits. Assuming the standard 1 byte = 8 bits, 1 pebibyte (PiB) is equal to 8 pebibits (Pib). Both use the binary prefix 'pebi-' (250).
Why is PiB used less often than PB in marketing?
Marketing materials for large storage systems often use the decimal prefix (PB, EB) because it results in a larger-looking number for capacity compared to the binary prefix (PiB, EiB) for the same amount of physical storage. For example, 1015 bytes is marketed as 1 PB, while an OS might report a similar capacity using PiB (1 PB is approximately 0.888 PiB). Using decimal units allows manufacturers to advertise higher, rounder numbers, even though technical contexts often rely on binary measurements.
About Exabyte (EB)
How many bytes are in an exabyte (EB)?
There are exactly 1,000,000,000,000,000,000 bytes (one quintillion bytes, or 10¹⁸ bytes) in 1 exabyte (EB). This is the official SI definition. For perspective, this is enough storage to hold:
- All books ever written: ~500,000 times over
- Every photo ever taken: ~50,000 times over
- 50,000 years of continuous HD video recording
- The complete DNA sequence of every human on Earth: ~7.5 million times over
How many petabytes are in an exabyte?
There are exactly 1,000 petabytes (PB) in 1 exabyte (EB). This follows the SI decimal standard where each prefix increases by 1,000. Therefore:
- 1 EB = 1,000 PB
- 1 PB = 1,000 TB
- 1 TB = 1,000 GB
- So 1 EB = 1,000 × 1,000 × 1,000 GB = 1,000,000,000 GB
How many terabytes are in an exabyte?
There are 1,000,000 terabytes (TB) in 1 exabyte (EB). Using the conversion:
- 1 EB = 1,000 PB
- 1 PB = 1,000 TB
- Therefore: 1 EB = 1,000 × 1,000 TB = 1,000,000 TB
This means 1 EB could theoretically store the entire iTunes music library (50 million songs) approximately 20,000 times, or store 1 million typical PC hard drives worth of data.
What is the difference between EB and EiB?
EB (exabyte) equals exactly 1,000,000,000,000,000,000 bytes (10¹⁸) using the SI decimal prefix system. EiB (exbibyte) equals exactly 1,152,921,504,606,846,976 bytes (2⁶⁰) using the IEC binary prefix system. An exbibyte is approximately 15.3% larger than an exabyte (1 EiB ≈ 1.153 EB).
This distinction matters at exabyte scale:
- Cloud storage providers advertise in EB (decimal)
- Technical specifications may use EiB (binary)
- 100 EB of cloud storage = 86.7 EiB of actual binary capacity
How much data is created globally each year?
