To convert gigabits to petabytes, 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.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications.
PB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Gigabits to Exabytes.
1 Gb = 0.000000125 PB (using SI decimal standard) — or equivalently, 1 PB = 8,000,000Gb.

SI Decimal Prefixes: How Gb to PB Is Calculated
Both gigabits and petabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Gb = 0.000000125 PB. 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 |
|---|---|---|---|
| Gigabit (Gb) | SI decimal | 1,000 | 1,000,000,000 bits |
| Petabyte (PB) | SI decimal | 1,000 | 8.000 × 10¹⁵ bits |

FAQs: Gigabit to Petabyte Conversion
6 questions Quick answers on converting gigabits to petabytes, using the same factors as the converter above.
-
How many petabytes are in 1 gigabit?
1 Gb = 0.000000125 PB
1 Gigabit (Gb) equals 0.000000125 Petabytes using the SI decimal standard.
-
How many gigabits are in 1 petabyte?
1 PB = 8,000,000 Gb
1 Petabyte (PB) equals 8,000,000 Gigabits.
-
How do I convert gigabits to petabytes?
Gb × 0.000000125 = PB
Multiply the gigabit value by 0.000000125 to get petabytes. For example, 10 Gb = 0.00000125 PB. To convert back (vice versa), multiply petabytes by 8,000,000.
-
Is a gigabit bigger than a petabyte?
PB is 8,000,000× larger than Gb
No. 1 Gb = 0.000000125 PB, so the petabyte is larger — 1 PB = 8,000,000 Gb.
-
Does Gb to PB use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both gigabits and petabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Gb = 0.000000125 PB. 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 Gigabit (Gb) commonly used for?
Common uses of the gigabit (Gb) include: Fiber internet speeds, enterprise networking, 10GbE connections.
