How to Convert Petabytes to Exbibytes
To convert petabytes (decimal/SI) to exbibytes (binary/IEC), multiply by 0.000867361738. Decimal units use base 1,000, while binary units use base 1,024. Related: EiB to PB calculator.
PB is a decimal (SI) unit—what storage manufacturers advertise. 1 PB = 1,000 of the smaller unit. Check out our PB to KB converter.
EiB is a binary (IEC) unit—what operating systems often display. 1 EiB = 1,024 of the smaller unit. Use our Kib to EiB.
1 PB = 0.000867361738 EiB (using SI decimal standard) — or equivalently, 1 EiB = 1,152.921505PB.
PB to EiB Conversion Formula
// Convert PB to EiB
EiB = PB × 0.000867361738

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. Related: Kibibits in Yobibytes.
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: converting Yobibytes Per Second to Zebibits Per Second.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives See also: PB to ZiB conversion rate.
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 Exbibyte (EiB)? Definition and Uses
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Related: calculate TiB to EiB.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. See also: how many Exabytes in a Pib.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity Use our how many KB/s in Megabits Per Second.
1 EiB = 9 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exbibyte can be abbreviated as EiB; for example, 1 exbibyte can be written as 1 EiB.

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