How to Convert Petabytes to Bytes
To convert petabytes to bytes, multiply by 1.000000000000e+15. This gives you the equivalent storage size in the target unit. Check out our convert B to Petabytes.
PB: A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. You might also need: Petabytes to TiB calculator.
B: A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). You might also need: EiB to Bytes converter.
1 PB = 1.000000000000e+15 B (using SI decimal standard) — which means there are 1.000000000000e+15bytes in every petabyte.
PB to B Conversion Formula
// Convert PB to B
B = PB × 1.000000000000e+15
// Reverse: Convert B to PB
PB = B × 1.000000e-15Petabyte to Byte Conversion Examples
100 PB = 1.000000000000e+17 B
256 PB = 2.560000000000e+17 B
500 PB = 5.000000000000e+17 B
1,000 PB = 1.000000000000e+18 B

What Is a Petabyte (PB)? Definition and Uses
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. Try the Exbibits to Mebibytes conversion.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. You might also need: convert Megabits Per Second to Terabytes Per Second.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives See also: Petabytes to Yottabytes calculator.
1 PB = 8 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The petabyte can be abbreviated as PB; for example, 1 petabyte can be written as 1 PB.
What Is a Byte (B)? Definition and Uses
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). See also: Zettabytes to Bytes converter.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: Zebibits to Kibibits.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) You might also need: Pbps → GB/s.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.

SI Decimal vs Binary: Why Two Different Standards?
When converting petabytes to bytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
