View the zettabyte data unit pageHow to Convert Exabytes to Zettabytes
To convert exabytes to zettabytes, divide by 1,000 (using SI decimal). Both units measure storage capacity—the difference is scale.
EB: An exabyte is 1,000 petabytes or 10^18 bytes. Used to measure global internet traffic and massive data volumes.
ZB: A zettabyte is 1,000 exabytes or 10^21 bytes. Used to measure total global data storage. Related: Terabytes to Terabits.
1 EB = 0.001 ZB (using SI decimal standard) — or equivalently, 1 ZB = 1,000EB.
EB to ZB conversion rate: 1 exabyte equals 0.001zettabytes — the standard exabyte to zettabyte data storage conversion used by this calculator.

- Use the swap control to reverse the calculation and convert zettabytes back into exabytes.
EB to ZB Conversion Formula
Here's the exact EB to ZB formula in copy-paste-ready form — multiply by 0.001 to go from exabytes to zettabytes, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert EB to ZB
ZB = EB × 0.001
// Reverse: Convert ZB to EB
EB = ZB × 1,000

SI Decimal vs Binary: Why Two Different Standards?
When converting exabytes to zettabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.
Want to skip the ambiguity entirely? Exbibyte (EiB) and Zebibyte (ZiB) are the IEC binary-only siblings of exabyte and zettabyte — always base 1,024, no dual-standard guessing. See the EiB to ZiB converter.
FAQs: Exabyte to Zettabyte Conversion
How many zettabytes are in 1 exabyte?
1 Exabyte (EB) equals 0.001 Zettabytes using the SI decimal standard, or 0.0009765625 ZB using the binary (IEC) standard.
How do I convert exabytes to zettabytes?
Multiply the exabyte value by 0.001 to get zettabytes. For example, 10 EB = 0.01 ZB.
Is a exabyte bigger than a zettabyte?
No. 1 EB = 0.001 ZB, so the zettabyte is larger — 1 ZB = 1,000 EB.
What is Exabyte (EB) commonly used for?
Global internet traffic, hyperscale data centers, worldwide digital data estimation.
