How to Convert Gibibytes to Petabytes
To convert gibibytes (binary/IEC) to petabytes (decimal/SI), multiply by 0.000001073741824. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales. See also: how many Gibibytes in a PB.
GiB is a binary (IEC) unit where 1 GiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations. Related: how many Tib in Gibibytes.
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. See also: Nibbles to PB.
1 GiB = 0.000001073741824 PB (using SI decimal standard) — or equivalently, 1 PB = 931,322.574615GiB.
GiB to PB Conversion Formula
// Convert GiB to PB
PB = GiB × 0.000001073741824
// Reverse: Convert PB to GiB
GiB = PB × 931,322.574615

What Is a Gibibyte?
A gibibyte is 1,024 mebibytes or 1,073,741,824 bytes. This is what operating systems actually display for storage. Try the convert ZiB to Yobibytes.
The gibibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Check out our Gibibits Per Second to bps calculator.
Common uses: Windows/macOS file sizes, SSD actual capacity, RAM modules Check out our GiB to Pebibytes converter.
1 GiB = 9 × 10⁹ bits = 1 × 10⁹ bytes.
The gibibyte can be abbreviated as GiB; for example, 1 gibibyte can be written as 1 GiB.
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. Learn more: Pebibytes to Petabytes conversion.

SI Decimal vs Binary: Why Two Different Standards?
When converting gibibytes 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 |
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.
