How to Convert Pebibytes to Exabytes
To convert pebibytes (binary/IEC) to exabytes (decimal/SI), multiply by 0.001125899907. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales. Related: calculate EB to PiB.
PiB is a binary (IEC) unit where 1 PiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations. Check out our PiB to Pb conversion rate.
EB is a decimal (SI) unit where 1 EB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. See also: converting Exbibits to Exabytes.
1 PiB = 0.001125899907 EB (using SI decimal standard) — or equivalently, 1 EB = 888.1784197001PiB.
PiB to EB Conversion Formula
// Convert PiB to EB
EB = PiB × 0.001125899907
// Reverse: Convert EB to PiB
PiB = EB × 888.1784197001

What Is a Pebibyte?
A pebibyte is 1,024 tebibytes or 2^50 bytes. Used for large-scale enterprise storage in binary terms. Use our Megabytes in Bytes.
The pebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Try the bps to KB/s.
Common uses: Enterprise SAN storage, data center capacity planning, cloud infrastructure Learn more: PiB to MB converter.
1 PiB = 9 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The pebibyte can be abbreviated as PiB; for example, 1 pebibyte can be written as 1 PiB.
What Is a Exabyte?
An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes. Related: GB to EB calculator.
The exabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: convert Eib to Kb.
Common uses: Global internet traffic, hyperscale data centers, worldwide digital data estimation You might also need: ZiB/s → Yibps.
1 EB = 8 × 10¹⁸ bits = 1 × 10¹⁸ bytes.
The exabyte can be abbreviated as EB; for example, 1 exabyte can be written as 1 EB.

SI Decimal vs Binary: Why Two Different Standards?
When converting pebibytes to exabytes, 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 PiB to EB
Common scenario: Reconciling the difference between what drive manufacturers advertise and what your operating system displays. Try the Pebibytes to Yobibits.
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. See also: how many Exabytes in a ZB.
