Petabytes to Gigabits formula
To convert petabytes to gigabits, multiply by 8000000.
Gb = PB × 8000000
Why this factor: the petabyte and the gigabit are both defined against the byte, so dividing one definition by the other gives 8000000 directly. Both definitions are set out in full below.
To go the other way, divide by 8000000 — or use the Gigabits to Petabytes converter, which is the same calculation reversed.
Worked example
Given 4 PB, multiplying by 8000000 yields 32000000 Gb.
4 PB × 8000000 = 32000000 Gb
The converter above does this for any value you type, in either direction.
What is a petabyte?
A petabyte is a thousand terabytes — the scale of large-scale data infrastructure.
Definition: Exactly 1×10¹⁵ bytes under SI prefixes.
Where it is used: Data-centre and cloud storage footprints, scientific datasets, and media archives.
What is a gigabit?
A gigabit is one billion bits, the unit of modern high-speed networking.
Definition: Exactly 1,000,000,000 bits, so exactly 125,000,000 bytes.
Where it is used: Gigabit Ethernet, fiber broadband tiers, and data-centre interconnects.
Petabytes vs Gigabits
The petabyte and the gigabit belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
