How to Convert Exbibytes to Petabytes
To convert exbibytes (binary/IEC) to petabytes (decimal/SI), multiply by 1,152.921505. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales. Use our PB to EiB calculator.
EiB is a binary (IEC) unit where 1 EiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations. Learn more: convert EiB to Tb.
PB is a decimal (SI) unit where 1 PB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Try the KB → PB.
1 EiB = 1,152.921505 PB (using SI decimal standard) — which means there are 1,152.921505petabytes in every exbibyte.
EiB to PB Conversion Formula
// Convert EiB to PB
PB = EiB × 1,152.921505
// Reverse: Convert PB to EiB
EiB = PB × 0.000867361738

What Is a Exbibyte?
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Related: Pebibits to Bits.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. You might also need: Pebibytes Per Second to Zebibits Per Second converter.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity You might also need: Exbibytes to Bytes calculator.
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.
What Is a Petabyte?
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. See also: convert Megabytes 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. Related: Gibibytes to Nibbles conversion.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives You might also need: Mbps to Gigabytes Per Second converter.
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 exbibytes 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 |
Why Does My Hard Drive Show Less Space Than Advertised?
This difference in standards explains the common "missing hard drive space" confusion.
Example: A "500 GB" Hard Drive
- Contains exactly: 500,000,000,000 bytes
- macOS (SI Decimal): Displays 500 GB (divides by 1,000³)
- Windows (Binary): Displays 465 GB (divides by 1,024³)
The Verdict: Same bytes, same drive—just different math. No space is actually missing.
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.
💡 Storage Engineer Tip
The ~9.95% difference between binary and decimal units compounds at each level. A 1 TB drive shows as 931 GiB in Windows because of this standard mismatch—no space is actually lost.

When to Convert EiB to PB
Common scenario: Reconciling the difference between what drive manufacturers advertise and what your operating system displays. Try the Exbibytes to ZB calculator.
Other situations include storage planning for calculating how much data fits in a given capacity, file management for understanding sizes across different scales, cost estimation for budgeting cloud storage, and backup planning for determining media requirements.
