How to Convert Gigabytes to Pebibytes
To convert gigabytes (decimal/SI) to pebibytes (binary/IEC), multiply by 0.00000088817842. Decimal units use base 1,000, while binary units use base 1,024. Check out our PiB to GB calculator.
GB is a decimal (SI) unit—what storage manufacturers advertise. 1 GB = 1,000 of the smaller unit. Check out our convert GB to TiB.
PiB is a binary (IEC) unit—what operating systems often display. 1 PiB = 1,024 of the smaller unit. See also: Pb → PiB.
1 GB = 0.00000088817842 PiB (using SI decimal standard) — or equivalently, 1 PiB = 1,125,900GB.
GB to PiB Conversion Formula
// Convert GB to PiB
PiB = GB × 0.00000088817842
// Reverse: Convert PiB to GB
GB = PiB × 1,125,900

What Is a Gigabyte?
A gigabyte is 1,000 megabytes or 1,000,000,000 bytes using the SI decimal standard. This is what hard drive manufacturers typically use. Check out our Bytes to Kibibits.
The gigabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our Mebibytes Per Second to Gibibits Per Second converter.
Common uses: Movies, video games, smartphone storage, USB drives, cloud storage plans Check out our Gigabytes to Gibibits calculator.
1 GB = 8 × 10⁹ bits = 1 × 10⁹ bytes.
The gigabyte can be abbreviated as GB; for example, 1 gigabyte can be written as 1 GB.
What Is a Pebibyte?
A pebibyte is 1,024 tebibytes or 2^50 bytes. Used for large-scale enterprise storage in binary terms. Check out our convert Tebibits to Pebibytes.
The pebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. See also: Nibbles to Petabits conversion.
Common uses: Enterprise SAN storage, data center capacity planning, cloud infrastructure Learn more: Ybps to Bytes Per Second 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.

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