PB to GB Conversion Formula
Here's the exact PB to GB formula in copy-paste-ready form — multiply by 1,000,000 to go from petabytes to gigabytes, or by 0.000001 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert PB to GB
GB = PB × 1,000,000
// Reverse: Convert GB to PB
PB = GB × 0.000001

SI Decimal vs Binary: Why Two Different Standards?
When converting petabytes to gigabytes, 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 above the converter.
Want to skip the ambiguity entirely? Pebibyte (PiB) and Gibibyte (GiB) are the IEC binary-only siblings of petabyte and gigabyte — always base 1,024, no dual-standard guessing. See the PiB to GiB converter.
FAQs: Petabyte to Gigabyte Conversion
How many gigabytes are in 1 petabyte?
1 Petabyte (PB) equals 1,000,000 Gigabytes using the SI decimal standard, or 1,048,576 GB using the binary (IEC) standard.
How do I convert petabytes to gigabytes?
Multiply the petabyte value by 1,000,000 to get gigabytes. For example, 10 PB = 10,000,000 GB.
Is a petabyte bigger than a gigabyte?
Yes. 1 PB = 1,000,000 GB, so the petabyte is the larger data storage unit.
What is Petabyte (PB) commonly used for?
Data centers, cloud storage providers, scientific research, enterprise archives.
