Frequently asked questions
What is the source unit in this conversion?
The source unit is the petabyte (PB), a decimal unit of digital storage equal to 1,000 terabytes, or 10^15 bytes.
What is the destination unit in this conversion?
The destination unit is the byte (B), a unit of digital storage equal to 8 bits, commonly used to represent a single character.
How do I convert petabytes to bytes?
Multiply the petabyte value by 1 × 1015 to get bytes. For example, 4 PB × 1 × 1015 = 4 × 1015 B.
Is the petabyte to byte conversion exact?
It's exact under the decimal (SI) definitions used here, where each decimal storage prefix is a fixed factor of 1,000 from the next (and bytes are a fixed factor of 8 from bits).
Where is this conversion commonly used?
It's used for describing file sizes, storage drive capacity, RAM, network bandwidth, and internet data plans or downloads.
Can I convert bytes back to petabytes?
Yes. Divide the byte value by 1 × 1015 to get petabytes.

About this conversion
This page converts petabytes (PB), a decimal unit of digital storage equal to 1,000 terabytes, or 10^15 bytes, into bytes (B), a unit of digital storage equal to 8 bits, commonly used to represent a single character.
This conversion is used constantly when checking file sizes, storage drive and memory capacity, network bandwidth, and mobile or broadband data plan allowances.
The formula is B = PB × 1 × 1015, based on the fixed relationship between these two digital storage units.
It's exact under the decimal (SI) definitions used here, where each decimal storage prefix is a fixed factor of 1,000 from the next (and bytes are a fixed factor of 8 from bits).
Digital storage prefixes follow the International System of Units (SI) for decimal units and the International Electrotechnical Commission (IEC) recommendations for binary units, keeping decimal and binary quantities unambiguous.
