How to Convert Petabits to Exbibytes
To convert petabits to exbibytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. Learn more: EiB to Pb conversion rate.
Pb measures data in bits—commonly used for memory addressing and low-level data specifications. You might also need: calculate Pb to B.
EiB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. See also: how many Exbibytes in a PiB.
1 Pb = 0.000108420217 EiB (using SI decimal standard) — or equivalently, 1 EiB = 9,223.372037Pb.
Pb to EiB Conversion Formula
// Convert Pb to EiB
EiB = Pb × 0.000108420217
// Reverse: Convert EiB to Pb
Pb = EiB × 9,223.372037

What Is a Petabit?
A petabit is 1,000 terabits or 10^15 bits. Used for measuring massive network throughput. You might also need: how many Kb in Kilobytes.
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. See also: Tebibits Per Second to Tbps.
Common uses: Internet exchange points, submarine cables, global network traffic See also: convert Pb to Zebibytes.
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.
What Is a Exbibyte?
An exbibyte is 1,024 pebibytes or 2^60 bytes. Used for hyperscale storage in binary measurements. Related: Tebibytes to EiB calculator.
The exbibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Learn more: Yb to Bits converter.
Common uses: Hyperscale data centers, global storage statistics in binary, cloud provider capacity Learn more: Bytes Per Second to Gibibytes Per Second conversion.
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 petabits 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 |
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.
