Convert Gigabits to Petabytes (Gbit to PB)
1 gigabit (Gbit) = 1.25 × 10⁻⁷ petabytes (PB). 1 PB = 8000000 Gbit. Example: 15 Gbit = 15 × 1.25 × 10⁻⁷ = 0.000001875 PB.

How to Convert Gigabit to Petabyte
- 1 Gbit = 1.25 × 10⁻⁷ PB
- 1 PB = 8000000 Gbit
- Example: convert 15 Gbit to PB: 15 Gbit = 15 × 1.25 × 10⁻⁷ PB = 0.000001875 PB
Formula
PB = Gbit ÷ 8000000
Derivation from SI units:
- 1 Gbit = 10⁹ bits.
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 Gbit = 1000000000 bit ÷ 8 × 10¹⁵ bit per PB = 1.25 × 10⁻⁷ PB
Both units are defined exactly, so the factor is exact. Gigabit definition: gigabit; Petabyte definition: petabyte.
Worked examples
- A reading of 16 Gbit converts to 0.000002 PB.
16 Gbit × 1.25 × 10⁻⁷ = 0.000002 PB - A value of 128 Gbit is 0.000016 PB.
128 Gbit × 1.25 × 10⁻⁷ = 0.000016 PB

Where it's used
Gigabits are used for DRAM and NAND flash chip densities, while petabytes appear in data centres and cloud providers. Both measure amount of digital information, so the conversion is a fixed factor.

Frequently asked questions
How many petabytes are in 1 gigabit?
1 Gbit = 1.25 × 10⁻⁷ PB.
How do I convert gigabits to petabytes?
Multiply the value in Gbit by 1.25 × 10⁻⁷, or divide it by 8000000. For example, 15 Gbit × 1.25 × 10⁻⁷ = 0.000001875 PB.
Is the Gbit to PB conversion exact?
Yes. Both units are defined exactly, and 1 Gbit is exactly 1.25 × 10⁻⁷ PB.
