What Is a Zettabyte (ZB)? Definition and Uses
A zettabyte is 1,000 exabytes or 10^21 bytes. Used to measure total global data storage. Related: B to Zib converter.
The zettabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Check out our Pbps to EB/s.
Common uses: Global data statistics, worldwide internet usage, total digital universe measurements Check out our Zettabytes in Bits.
1 ZB = 8 × 10²¹ bits = 1 × 10²¹ bytes.
The zettabyte can be abbreviated as ZB; for example, 1 zettabyte can be written as 1 ZB.
What Is a Pebibyte (PiB)? Definition and Uses
A pebibyte is 1,024 tebibytes or 2^50 bytes. Used for large-scale enterprise storage in binary terms. Related: converting Nibbles to Pebibytes.
The pebibyte is a IEC binary unit of digital information storage. It uses base 1,024 following the IEC (International Electrotechnical Commission) standard. Learn more: MB to KiB conversion rate.
Common uses: Enterprise SAN storage, data center capacity planning, cloud infrastructure Check out our calculate GiB/s to Tibps.
1 PiB = 9 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The pebibyte can be abbreviated as PiB; for example, 1 pebibyte can be written as 1 PiB.

SI Decimal vs Binary: Why Two Different Standards?
When converting zettabytes to pebibytes, 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 at the top of the calculator.
