How to Convert Gigabits to Petabytes
To convert gigabits to petabytes, multiply the data size by the following conversion ratio: 0.000000125 petabytes/gigabit.
Since one gigabit is equal to 0.000000125 petabytes, you can use this simple formula to convert:
The data size in petabytes is equal to the data size in gigabits multiplied by 0.000000125.
For example, here's how to convert 5 gigabits to petabytes using the formula above.
How Many Petabytes Are in a Gigabit?
There are 0.000000125 petabytes in a gigabit, which is why we use this value in the formula above.
Our gigabit to petabyte calculator automatically converts your data size measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Gigabits and petabytes are both units used to measure data size. Keep reading to learn more about each unit.
What Is a Gigabit?
A gigabit is a unit of data size equal to 125,000,000 bytes (B), the base unit for data size. Equal to 1,000,000,000 bits (125 MB). [1]
The gigabit is classified as a metric and SI-compatible unit of data size. Gigabits can be abbreviated as Gb; for example, 1 gigabit can be written as 1 Gb.
In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigabit (Gb) a convenient decimal multiple of the byte (B).
In practice, gigabits (Gb) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Petabyte?
A petabyte is a unit of data size equal to 1e+15 bytes (B), the base unit for data size. SI decimal standard: 10¹⁵ bytes (1,000 TB). [2]
The petabyte is classified as a metric and SI-compatible unit of data size. Petabytes can be abbreviated as PB; for example, 1 petabyte can be written as 1 PB.
In the metric system, "peta" is the standard SI prefix for quadrillions, or 10¹⁵. This makes the petabyte (PB) a convenient decimal multiple of the byte (B).
In practice, petabytes (PB) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting data size between gigabits (Gb) and petabytes (PB), keep full floating-point precision (1 Gb = 0.000000125 PB; 1 PB = 8,000,000 Gb) during intermediate calculations and round only the final petabyte figure to match your instrument tolerance.
