To convert petabits to gigabytes, 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.
Pb measures data in bits—commonly used for memory addressing and low-level data specifications.
GB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Kilobytes to Kilobits.
1 Pb = 125,000 GB (using SI decimal standard) — which means there are 125,000gigabytes in every petabit.
Pb to GB conversion rate: 1 petabit equals 125,000gigabytes — the standard petabit to gigabyte data storage conversion used by this calculator.

SI Decimal Prefixes: How Pb to GB Is Calculated
Both petabits and gigabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Pb = 125,000 GB. This is the convention behind advertised link speeds and drive specifications. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Petabit (Pb) | SI decimal | 1,000 | 1.000 × 10¹⁵ bits |
| Gigabyte (GB) | SI decimal | 1,000 | 8,000,000,000 bits |

FAQs: Petabit to Gigabyte Conversion
6 questions Quick answers on converting petabits to gigabytes, using the same factors as the converter above.
-
How many gigabytes are in 1 petabit?
1 Pb = 125,000 GB
1 Petabit (Pb) equals 125,000 Gigabytes using the SI decimal standard.
-
How many petabits are in 1 gigabyte?
1 GB = 0.000008 Pb
1 Gigabyte (GB) equals 0.000008 Petabits.
-
How do I convert petabits to gigabytes?
Pb × 125,000 = GB
Multiply the petabit value by 125,000 to get gigabytes. For example, 10 Pb = 1,250,000 GB. To convert back (vice versa), multiply gigabytes by 0.000008.
-
Is a petabit bigger than a gigabyte?
Pb is 125,000× larger than GB
Yes. 1 Pb = 125,000 GB, so the petabit is the larger data storage unit.
-
Does Pb to GB use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both petabits and gigabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Pb = 125,000 GB. Because one unit counts bits and the other bytes, the factor also includes a factor of 8. The binary (IEC) versions count in base 2 steps of 1,024 instead.
-
What is Petabit (Pb) commonly used for?
Common uses of the petabit (Pb) include: Internet exchange points, submarine cables, global network traffic.
