How to convert petabytes to bytes
To convert a measurement in petabytes to bytes, multiply the value by 1.000000e+15. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 PB to bytes: 5 × 1.000000e+15 = 5.000000e+15 B.
What is a petabyte?
A petabyte is 1,000,000,000,000,000 bytes (1,000 terabytes) under the SI decimal convention. The binary equivalent is the pebibyte (PiB). The petabyte is the scale of large enterprises and cloud providers. Notable milestones include estimates that major platforms ingest multiple petabytes of new data every day.
Common uses of petabytes include: Data-center and cloud-storage capacity; Big-data analytics and data lakes; Scientific datasets (genomics, astronomy); Large-scale media streaming archives.
What is a byte?
A byte is a unit of digital information consisting of 8 bits. It is the standard addressable unit of memory and can represent a single text character. The byte was defined by Werner Buchholz in 1956 during the design of the IBM Stretch computer. Eight bits became the de facto standard, enough to encode a character in early text encodings like ASCII.
Common uses of bytes include: File sizes and memory addressing; Text character storage (1 byte per ASCII character); Low-level programming and data structures; Baseline unit for all larger storage measures.

Frequently asked questions
How many bytes are in one petabyte?
One petabyte (PB) equals 1.000000e+15 bytes (B). Multiply any value in petabytes by 1.000000e+15 to convert to bytes.
How do I convert petabytes to bytes?
Multiply the value in petabytes by 1.000000e+15. For example, 5 PB × 1.000000e+15 = 5.000000e+15 B.
How do I convert bytes to petabytes?
Multiply the value in bytes by 1.000000e-15, or divide by 1.000000e+15. Use the swap button on the converter above to reverse the direction.
Is the petabyte to byte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for petabytes to bytes?
The formula is: B = PB × 1.000000e+15. This comes from the definition of both units relative to the byte.
