How to Convert Pebibytes to Petabits
To convert pebibytes to petabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. See also: Petabits in Pebibytes.
PiB is a byte-based unit used for measuring file sizes and storage capacity. Check out our PiB to Tib.
Pb is a bit-based unit—multiply bytes by 8 to get bits. Learn more: EiB to Pb converter.
1 PiB = 9.0071992547 Pb (using SI decimal standard) — which means there are 9.0071992547petabits in every pebibyte.
PiB to Pb Conversion Formula
// Convert PiB to Pb
Pb = PiB × 9.0071992547
// Reverse: Convert Pb to PiB
PiB = Pb × 0.111022302463

What Is a Pebibyte?
A pebibyte is 1,024 tebibytes or 2^50 bytes. Used for large-scale enterprise storage in binary terms. Try the Tib to ZB calculator.
The pebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Related: convert TB/s to PiB/s.
Common uses: Enterprise SAN storage, data center capacity planning, cloud infrastructure Learn more: PiB → PB.
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 Petabit?
A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. Check out our Terabytes to Petabits.
The petabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our Gigabits to Terabits converter.
Common uses: Internet exchange points, submarine cables, global network traffic See also: Yobibits Per Second to Petabits Per Second calculator.
1 Pb = 1 × 10¹⁵ bits = 125 × 10¹² bytes.
The petabit can be abbreviated as Pb; for example, 1 petabit can be written as 1 Pb.

SI Decimal vs Binary: Why Two Different Standards?
When converting pebibytes to petabits, 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.
