Bytes (B) to Petabytes (PB) Converter
The Bytes (B) to Petabytes (PB) Converter turns your Byte (B) value into Petabytes (PB). Type your storage value in the input field — 1 B = 1.000000e-15 PB, calculated across both decimal (SI) and binary (IEC) standards.

How to Convert Bytes to Petabytes
To convert bytes to petabytes, divide by 1.000000000000e+15. This gives you the equivalent storage size in the target unit. Check out our convert PB to Bytes.
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). Use our Bytes to Tb.
PB: A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. See also: how many PB in Megabytes.
1 B = 1.000000e-15 PB (using SI decimal standard) — or equivalently, 1 PB = 1.000000000000e+15B.
B to PB Conversion Formula
// Convert B to PB
PB = B × 1.000000e-15
// Reverse: Convert PB to B
B = PB × 1.000000000000e+15Byte to Petabyte Conversion Examples
100 B = 1.000000e-13 PB
256 B = 2.560000e-13 PB
500 B = 5.000000e-13 PB
1,000 B = 1.000000e-12 PB
2,048 B = 2.048000e-12 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). Try the how many Gibibits in a Eb.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Try the calculate bps to KB/s.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) You might also need: B to Pib conversion rate.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 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. You might also need: converting Exbibits to Petabytes.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: Yobibits in Yottabits.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives You might also need: ZiB/s to Yibps.
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.

SI Decimal vs Binary: Why Two Different Standards?
When converting bytes to petabytes, 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.
