How to Convert Petabytes to Bits
To convert petabytes to bits, multiply the data size by the following conversion ratio: 8e+15 bits/petabyte.
Since one petabyte is equal to 8e+15 bits, you can use this simple formula to convert:
The data size in bits is equal to the data size in petabytes multiplied by 8e+15.
For example, here's how to convert 5 petabytes to bits using the formula above.
How Many Bits Are in a Petabyte?
There are 8e+15 bits in a petabyte, which is why we use this value in the formula above.
Our petabyte to bit calculator automatically converts your data size measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Petabytes and bits are both units used to measure data size. Keep reading to learn more about each unit.
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). [1]
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.
What Is a Bit?
A bit is a unit of data size equal to 1/8 of a byte (0.125 B). Basic binary digit (1/8 of a byte). [2]
The bit is classified as an IEC binary unit of data size. Bits can be abbreviated as b; for example, 1 bit can be written as 1 b.
When working with bits (b) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, bits (b) are widely used across standard data size applications within IEC binary workflows, engineering documentation, and technical data sheets.
When converting data size between petabytes (PB) and bits (b), keep full floating-point precision (1 PB = 8e+15 b; 1 b = 1.25e-16 PB) during intermediate calculations and round only the final bit figure to match your instrument tolerance.
