About Converting PiBs to Bytes
PiB and Byte are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: PiB digital storage unit, and byte digital storage unit.
Formula
bytes = pibs × 1.1259e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 pib equals 9.007199e+15 base units, and 1 byte equals 8 base units, so dividing one by the other gives the direct pib-to-byte factor of 1.1259e+15.
Simple example
1 PiB × 1.1259e+15 = 1.1259e+15 B
1 pib = 1.1259e+15 bytes.
Real-world example
500 PiB × 1.1259e+15 = 5.6295e+17 B
500 pibs = 5.6295e+17 bytes.

Reverse conversion: Byte to PiB
1.1259e+15 B × 8.881784e-16 = 1.000000083 PiB
1.1259e+15 bytes = 1.000000083 pibs.
pibs = bytes × 8.881784e-16

Understanding the PiB (PiB)
PiB digital storage unit.
Understanding the Byte
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
Where it's used: Universal in computing
Uses of the Byte today
- Fundamental unit for file sizes and memory addressing
- Base unit from which all larger storage units (KB, MB, GB) are derived
History of the Byte
The byte emerged in the 1950s-60s as computer architectures converged on 8 bits as a practical size for representing a single character; IBM's System/360 (1964) was influential in cementing the 8-bit byte as an industry standard.
Historical origin. Byte was not the invention of a single named person; it developed through the process described above.
Byte — sources
- IEC 80000-13 — Defines the byte and its relationship to the bit.

Frequently asked questions
How many bytes are in 1 pib?
1 pib equals 1.1259e+15 bytes, using the exact defined conversion factor rather than an estimate.
How do I convert pib to byte?
Multiply the pib value by 1.1259e+15. The converter above does this instantly to whatever precision you set.
How do I convert byte back to pib?
Use the reverse factor: 1 byte equals 8.881784e-16 pibs. You can also use the swap control in the converter above to flip the direction instantly.
What is a pib?
PiB (PiB) is a unit of digital storage.
What is a byte?
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
Is the pib to byte conversion exact?
Yes. Both pib and byte are defined by fixed standards rather than physical artifacts, so the factor of 1.1259e+15 used above is exact to as many digits as you choose to display.
