Frequently asked questions

What is the source unit in this conversion?

The source unit is the exabyte (EB), a decimal unit of digital storage equal to 1,000 petabytes, or 10^18 bytes.

What is the destination unit in this conversion?

The destination unit is the zettabyte (ZB), a decimal unit of digital storage equal to 1,000 exabytes, or 10^21 bytes.

How do I convert exabytes to zettabytes?

Multiply the exabyte value by 0.001 to get zettabytes. For example, 4 EB × 0.001 = 0.004 ZB.

Is the exabyte to zettabyte 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 zettabytes back to exabytes?

Yes. Divide the zettabyte value by 0.001 to get exabytes.

About this conversion

This page converts exabytes (EB), a decimal unit of digital storage equal to 1,000 petabytes, or 10^18 bytes, into zettabytes (ZB), a decimal unit of digital storage equal to 1,000 exabytes, or 10^21 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 ZB = EB × 0.001, 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.
