Frequently asked questions
What is the source unit in this conversion?
The source unit is the zettabyte (ZB), a decimal unit of digital storage equal to 1,000 exabytes, or 10^21 bytes.
What is the destination unit in this conversion?
The destination unit is the petabyte (PB), a decimal unit of digital storage equal to 1,000 terabytes, or 10^15 bytes.
How do I convert zettabytes to petabytes?
Multiply the zettabyte value by 1,000,000 to get petabytes. For example, 4 ZB × 1,000,000 = 4,000,000 PB.
Is the zettabyte to petabyte 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 petabytes back to zettabytes?
Yes. Divide the petabyte value by 1,000,000 to get zettabytes.

About this conversion
This page converts zettabytes (ZB), a decimal unit of digital storage equal to 1,000 exabytes, or 10^21 bytes, into petabytes (PB), a decimal unit of digital storage equal to 1,000 terabytes, or 10^15 bytes.
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 PB = ZB × 1,000,000, 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.
